Many users of laptops face that sound does not work on their devices. Problems can occur due to software or hardware components. In our current article will be presented all possible Causes of lack of sound on a computer and various solutions to the problem .
Agree that the lack of sound causes explicit discomfort during the operation of the laptop. It is impossible to listen to your favorite music, you can not fully enjoy watching the film, it is impossible to arrange a voice conference in some messenger and so on. To start, Consider several main reasons why there is no sound on a laptop :
The system mixer is turned off;
Availability of incorrect audio settings in an operating system or a specific player;
Disable WindowsAudio service;
Incorrectly specified configurations for equipment in BIOS;
Presence of viruses on your PC;
The malfunction is caused by the absence of codecs;
There was a failure in the drivers, for example, they flew after reinstalling the OS;
The performance of acoustic speakers is broken, headphones are broken;
Breakdown of the built-in laptop speakers, faulty microphone, plug, connector, cable, and so on;
The sound card failed.
To correct the problem in the last two cases, you will need to contact the service center for the proper replacement for one or another component. All other situations are solved in place without leaving home! The main thing is not to panic and follow our step-by-step instructions.
Setting the volume from the notification area
First of all, make sure that there was no accident to press the MUTE key, because it translates the computer into a silent mode. In active condition, it looks like a loudness icon with a cross.
Hot keys very much cause the loss of a laptop sound. Fortunately, to restore sound you need to press one button. Regardless of whether you use modern Microsoft Windows 10 or outdated XP, click the left button on the loudspeaker icon in the tray (right at the bottom of the screen, next to the date and time) and check the volume controls. Slide the slider to the maximum value.
Pay attention to the mechanical sound control buttons "VOLUME +", "VOLUME-". Their location may depend on the specific laptop model, for example, on computer equipment HP, ASUS, Acer, Dell and Lenovo they are on the top panel. If it did not work out to change the volume level, try pressing the FN + key combination of the speaker buttons.
We try to connect speakers after the disappearance of the sound
To eliminate damage to internal speakers, you will need to connect external columns, headphones or portable devices that support the sound playback option. Open a music file in any player and check whether the audio track is played. Was it possible to eliminate the problem? It means that the built-in laptop speaker is damaged, you must contact the computer workshop for subsequent repair or replacement of components.
There are also situations with damage to the headphones for headphones, therefore interference or a complete absence of sound may also occur. The system can issue messages that it is turned off in the audio disconnect, it is connected.
Many users are wondering Why does the sound on the laptop periodically disappear? If the case is not in a broken connector, most likely, the problem is in the incorrect operation of the sound card, in this case you should contact the service center. The only way out of the situation without calling a specialist is to connect an external audio card via USB port.
We use the built-in application from the manufacturer of the audio device
Almost any OS has a special utility, separately installed by a sound card manufacturer (for example, Realtek High Definition Audio).
To open a mixer need to do the following:
Clicking PCM on an arrow icon, located at the bottom right of the taskbar, near the battery indicator;
Right-click on the AudioControl icon and select "Dispatcher" (shown in the photo below);
In the window that appears, you can set the required configurations for the audio device.
If you have sounded sound on your computer, but there is no such function, we recommend re-installing or updating the audio driver. Perhaps it will help to figure out the loss of sound.
Check, install and update drivers
Open the "Start" menu and in the search bar, enter the Device Manager or DevmGMT.msc, go to the found section;
In the next interface, find and expand the tab called "Sound, Gaming and Video Controls";
After you have found your audio device, click on it right key mouse if the hardware is disabled, you should select "Enable".
If the yellow exclamation mark is displayed opposite the audio device, it works incorrectly, which means it is necessary to reinstall the driver. In most cases, it helps.
By right-clicking on your hardware, click "Update Drivers";
Wait for the successful completion of the update procedure, after which we advise you to restart the computer.
What if OS could not automatically find an audio driver?
Install the driver can be installed from a disk attached to the motherboard.
If the disk is missing, download the necessary software for the controller from the site of the manufacturer of a sound card or laptop;
After starting the installer, install the driver;
The last step is to restart the laptop.
How to work with windows audio service?
Go to the "Control Panel" (for more convenience, switch the viewing mode from the "category" to "large icons") and go to "Administration";
Find the "Services" section, click on it with a double mouse click;
The list of services opens, look at the Windows Audio item, its state must be executed (as shown in the screenshot);
If the service is stopped, you should click on it twice and go to "Properties";
Opposite the field "Type of Start", select "automatically" and click "Run".
If, after the next boot of the computer, WindowsAudio will be stopped, you can manually add it to autorun. Then she stops off.
How to configure sound card settings in BIOS?
At the time of switching on or rebooting the Lapplet, before the emblem appears, you need to press a key several times F2. or Delete if it did not work, reboot again;
If you cannot log in to BIOS, it can be other buttons, for example: F10, F11, F12 and even special key combinations. For more information on the launch methods of Basic Input / Output System on different models of laptops, can be found in
When you see the BIOS interface, go to the Devices Configuration section.
We are looking for an item with the word Audio, for example: High Definition Audio and pay attention to the position opposite it;
If the Disabled parameter is set, your audio equipment is turned off, it is enough to change the parameter to enabled to activate it;
Do not forget to save the changes by pressing the F10 key;
Ready, you were able to restore the sound on your laptop!
Additional ways to troubleshoot
If nothing of the above helped get rid of problems with sound, try the following options.
The first thing you can do is to see the task manager
At the same time, clamp a Ctrl + Alt + Del combination and select the corresponding item;
Go to the "Services" tab, here you can see various launched and stopped processes;
We find the process of interest to us (for example, RTK or Realtek Audio Service) and check whether it is not stopped;
If the application is turned off, click on it right mouse button and select "Run" in the context menu that appears.
Perhaps an error lies in an incorrectly set reproduction device, try to eliminate
Suppose you connected the HDMI TV, smartphone, tablet, and so on, your task is to specify the correct audio campaign equipment;
Right-click on the volume icon in the system tray;
In a small window, select "Playback devices";
Set your default loudspeaker.
It happens that the lack of sound is connected with only one or more applications or sites
We go into the program, a media player, for example, a video player for HD video files, or open a website;
Check the regulator if it is crossed out or set at a minimum, you should use the slider to increase the volume;
As an example, options with a social network VKontakte and YouTube video hosting are given.
If the sound disappeared after installing or updating a specific software
Enter the control panel and open the Security and Service Center;
In field "Equipment and sound" n AM Need a "Troubleshooting Sound Playback" tool (only works with administrator rights), click on it and follow further instructions in the diagnostic interface.
You can also try to roll back the system until the time when the normal audio operation was observed.
If the sound is missing when watching video
It is recommended to download and install audio codecs;
By the way, the set of the desired codecs is present in the programs K-Lite Codec Pack or Media Player Codec Pack , you can download them from here;
To make everything correctly, it will be necessary to restart OS.
The "Device is used by another application" appears.
We look at the running applications in the tray, you can remove unnecessary;
It will not be too much to go to the "Task Manager";
In the Processes tab, remove extra tasks;
Switch to the "Startup" tab and disconnect unwanted programs.
One of the most "unusual" failures faced by Windows Windows 7, 8 and 10. The sound disappears if the computer moved to sleep mode with inserted headphones, then they disconnected them, and then brought a laptop from sleep mode.
We repeat the operation in the reverse order;
We go into sleep mode and will leave it with already connected headphones;
Now disconnect the headphones;
The speakers must earn correctly.
To check, try to increase the volume or insert headphones. The impact on the volume scale is usually accompanied by a sound effect.
I never thought that with sound could be so many problems! It is indisputable, but this is a fact - a fairly large number of laptop users face that one day, the sound on their device disappears ...
It may occur for various reasons and, most often, the problem can be eliminated independently, fighting in the Windows settings and drivers (thanks to which, save on computer services). In this article, I collected some of the most frequent reasons why the sound on laptops disappears (check and eliminate which even the novice user of the PC!). So…
Cause # 1: Adjusting the volume in Windows
Of course, I understand that many can express discontent - " that it is quite ... »For such an article. But all the same, many users do not know that the sound in Windows is regulated not only by the slider, which is located next to the clock (see Fig. 1).
Fig. 1. Winows 10: Volume.
If you click on the sound icon (located next to the clock, see fig. 1) Right-clicking, then several additional options will appear (see Fig. 2).
I recommend opening alternately as follows:
Mixer Volume : It allows you to set your volume in each application (for example, if you do not need a sound in the browser - it is possible to turn it out there;
Playback devices : In this tab, you can choose through which speakers or speakers to play sound (and in general, in this tab, all sound devices connected to the device are displayed. Moreover, sometimes even those you do not have! And imagine, sound can be served on non-existent devices ...).
Fig. 2. Sound settings.
В Mixer Volume Please note whether the sound is not reduced to a minimum in your running application. It is recommended to raise all the sliders up at least for the time of finding the causes and troubleshooting with sound (see Fig. 3).
Fig. 3. Mixer volume.
In the tab " Playback devices "Please note that you have maybe several devices (I have in fig. 4 just one device) - and If the sound "serves" is not the device , it may be the reason for the loss of sound. I recommend you check all devices displayed in this tab!
Fig. 4. Tab "Sound / Playback".
By the way, sometimes understand and find the causes of problems with sound helps the built-in Windows Master. To start it - simply, right-click on the sound icon in Windows (next to the clock) and start the appropriate master (as in Fig. 5).
Fig. 5. Troubleshooting Sound
Cause # 2: Drivers and their setup
One of the most frequent causes of problems with sound (and not only with it) are conflicting drivers (or the absence of these). To check their presence, I recommend to open device Manager : To do it enter into Windows Control Panel , then switch the display on Large icons And run this dispatcher (see Fig. 6).
Fig. 6. Running device manager.
Next, open the " Sound, Gaming and Video Devices ". Pay attention to all lines: there should be no exclamation of yellow signs and red crosses (which means that problems are observed with the drivers).
Fig. 7. Device Manager - the driver is all right.
By the way, I also recommend opening the "Unknown Devices" tab (if such). It is possible that you simply do not have the necessary drivers in the system.
Fig. 8. Device Manager- An example of a driving problem.
By the way, I also recommend checking the drivers in the Driver Booster utility (there is both free and paid version, differ in speed). The utility easily and quickly helps to check and find the necessary drivers (an example is shown in the screenshot below). What is convenient - so this is what you do not need to independently search for various software sites, the utility itself will compare the dates and find the desired driver, you will also remain just pressing the button and agree on its installation.

Fig. 9. Driver Booster - Driver Update.
Cause # 3: Not configured Sound Manager
In addition to the sound settings in the Windows itself, there is a sound manager in the system (almost always), which is installed with the drivers ( In most cases, this is REALTEK HIGH DEFINITION AUDIO ). And quite often, it is in it that can be set not the optimal settings that do sound not heard ...
How to find it?
Very simple: come in Windows Control Panel and then go to the tab " Equipment and sound ". Next, this tab should see the dispatcher, which is installed on your equipment. For example, on a laptop that I currently configure - an application has been installed Dell Audio. . This software needs to be opened (see Fig. 10).
Fig. 10. Equipment and sound.
Next, pay attention to the basic sound settings: first check the volume and checkboxes that can completely turn off the sound (see Fig. 11).
Fig. 11. Volume settings in Dell Audio.
Another important point: you need to check whether the laptop correctly determines the device connected to it. For example, you inserted headphones, and the laptop did not recognize them and work incorrectly with them. Result: There is no sound in headphones!
So that this is not - when connecting the same headphones (for example), a laptop, usually asks if he determined them correctly. Your task: Specify him correctly the audio device (which you connected). Actually, it happens in Fig. 12.
Fig. 12. Select a device connected to a laptop.
Cause # 4: A sound card operation is turned off in BIOS
In some laptops, you can turn off the audio card in the BIOS settings. So you are unlikely to hear the sound from your mobile "friend." Sometimes the BIOS settings can be "randomly" changed with ineptive actions (for example, when Windows is installed, not experienced users often change not only what they need ...).
Actions in order :
1. First go to the BIOS ( As a rule, you need to press the Del or F2 button immediately after turning on the laptop ). In more detail about which buttons to click, you can find out in this article: https://pcpro100.info/kak-voyti-v-bios-klavishi-vhoda/
2. Since the settings in the BIOS differ depending on the manufacturer, then it is difficult to give universal instructions. I recommend to go to all tabs and check all items in which the word is present " Audio. ". For example, in ASUS laptops there is a tab Advanced in which you need to translate into mode Enabled. (i.e. included) string High Definition Audio. (See Fig. 13).
Fig. 13. ASUS laptop - BIOS settings.
3. Next save the settings (most often the button F10 ) and leave the BIOS (button ESC ). After restarting the laptop - the sound should appear if the reason was the settings in the BIOS ...
Cause No. 5: Lack of some audio and video codecs
Quite often, the problem is observed when you try to play some movie or audio record. If there is no sound when opening video files or music (but in other applications there is sound) - the problem is on 99.9% Located with codecs!
I recommend to do this:
First delete all the old codecs from the system completely;
Next restart the laptop;
Install anew one of the following sets (find the link) in full extended mode (so you will have all the most necessary codecs in the system).
Sets of codecs for Windows 7, 8, 10 - https://pcpro100.info/luchshie-kodeki-dlya-video-i-audio-na-windows-7-8/
For those who do not want to establish new codecs into the system - there is another option, download and install a video player, which already contains all the most necessary to play the files of a wide variety of types. Such a player become popular enough, especially recently (and not surprisingly, who wishes to suffer with codecs?!). Link to an article about such a player will find below ...
Players working without codecs - https://pcpro100.info/proigryivateli-video-bez-kodekov/
Cause # 6: Problem with sound card
The latter on what I wanted to stop in this article is on the problems of a sound card (it can fail with sharp electricity jumps (for example, with zipper or welding)).
If this happened, in my opinion, the most optimal option is to use the outer sound card. Such cards are now available at the price ( Especially if you buy in some Chinese store ... at least it is much cheaper than looking for "native" ) And represent a compact device, the size of a little more than the usual flash drive. One of these external sound cards is presented in Fig. 14. By the way, such a card often provides sound much better than the built-in card in your laptop!
Fig. 14. External sound for laptop.
I finish on the sim article. By the way, if you have a sound, but it is quiet - I recommend using tips from this article: https://pcpro100.info/tihiy-zvuk-na-kompyutere/. Good job!
Loss of sound on a laptop does not always talk about a serious breakdown. Most often, solve the problem is detected independently in a few minutes. The main thing is to correctly determine the source of the failure - we will now help.
Before performing any actions to restore sound, reboot the system. This is the most banal council, but the practice shows that it often helps - at least minor system restarts eliminates without problems. The sound did not appear? We start diagnostics from the simplest settings.
On Windows there are several ways to control the volume of sound. The easiest - to press the left mouse button on the speaker icon, which is on the notifications panel near the date and time. A runner will appear, with which you can adjust the volume.
But here there is one feature - even if the volume of the device is installed at an acceptable level, in some sound applications may not be. This can be a problem if you do not know about other volume parameters.
Right-click on the speaker icon.
Click "Open Volume Mixer".
3. Test volume for system sounds and other applications.
Another way to control the volume is often used on the laptop - using hot keys. The default following combinations are installed:
Fn + F10 - Disable / enable sound.
Fn + F11 - Reduce volume.
Fn + F12 - increase the volume.
Keyboard shortcuts can change - for example, on one laptop I have sound control starts with F9, and F12 sends the device to hibernation mode. To not be mistaken, pay attention to the pictograms drawn on the keys. On some devices, the buttons can be deposited on the housing.
In addition, the volume settings are also in separate applications. In the Games, the noise level is set in the options, the sound is also available in the media players.
Select Device Device
Not the most obvious moment - the choice of default playback device. I ran into such a problem when I connected a monitor to a laptop via HDMI. The system has decided that it is necessary to transmit not only an image, but also the sound. But the monitor does not have speakers, so instead of music was silence. This problem is solved simply:
Right-click on the speaker icon on the notifications panel.
Open the "Playback Devices" section.
Find in the list of laptop speakers.
We highlight them and click on the "Default" button.
Apply the parameters.
If the speakers are highlighted in gray, then click on it right-click and select the "Enable" option. This method works on all versions of Windows. If you want to output the sound to an external device, we simply connect it and put the default use.
In the context menu of the speaker control, there is another useful item - "detect problems with sound." Pressing it starts the troubleshooting wizard. However, this method rarely helps determine the cause of the problem. Sometimes the wizard is even misleading by offering updating the drivers that are actually in order.
Enabling Windows Audio
The Windows Audio service is responsible for playing. If it is disabled, neither the addition of the volume, nor the choice of device by default will help.
Press the combination of Win + R to call the "Run" window.
Enter the Services.msc command.
3. We find in the list of Windows Audio services.
4. Open its properties with a double click.
5. I set the start type "automatically" and click "Run" if the service did not work.
6. Restart the laptop to apply the configuration.
Usually the service is not turned off by itself. But such a problem may occur when using various Windows twisers and accelerators, which in an attempt to optimize the system work with different services, turning off them or changing the start type.
Work with drivers
Drivers are required for sound card operation. This applies to both external devices and integrated into the motherboard. The lack of drivers or their conflict leads to the fact that there is no sound on a laptop. Check these reasons and, if necessary, eliminate errors.
1. Open the Device Manager. On Windows 10, you can right-click on the "Start" menu and select the appropriate item. Universal way - to start the dispatcher through the "Control Panel
2. Reveal the section "Sound, game and video devices".
3. We check that there is no exclamation mark near the sound card - this is an explicit mark about the problem.
4. The sound card may also be in the section "Unknown Devices". This happens if drivers are not installed in the system.
Even if there is no exclamation mark near the sound card, you still check the status of the drivers. To begin with, let's try to roll out them to eliminate possible conflicts:
Right-click on the sound card and open its properties.
Go to the Driver tab.
Click "roll back."
If you can not roll back the driver or it does not solve the problem, then update by software. To begin with, looking for a sound card driver on the website of the laptop manufacturer. It must be on the device model page. If you cannot find the driver from the manufacturer, we install universal:
In the properties of the sound card, go to the "Details" tab.
In the "Property" line, select the Item "Equipment ID".
Copy the first value.
4. Open the Devid.info website.
5. Insert the copied value into the search string.
6. Download the driver version, suitable operating system.
If the driver is running in the form of an executable file with the exe extension, you run it with a double click and install as a regular program for Windows. If you cannot install it so, we use another method:
Return to the properties of the sound card.
On the Driver tab, click "Update".
Select the "Run driver search on this computer" mode.
4. Click "Overview" and specify the path to the downloaded file.
5. After the installation is completed, restart the system.
If a sound card from REALTEK is used on the laptop, then we recommend installing also Realtekhigh Defender Audio Driver. This program is installed in two stages: Files are copied to the system, then the computer reboots, after which the installation begins.
Configure Sound Manager
On some laptops there is not only the driver of the Realtekhigh Defender Audio, but also the branded utility from the manufacturer. It can also be settings that cut the sound. Let's see how it works, on the example of the Dell Audio application. As can be seen from the name, it is a pre-installed program on some Dell laptop models.
Open the "Control Panel".
Go to the "Equipment and Sound" section.
Run the Dell Audio application.
On the main page, check that the sound is not turned off, and the volume is installed at an acceptable level.
Dell Audio has also settings for connecting devices. On the Advanced tab, we find the "connectors" section. It establishes a sound playback device - right as in the system parameters that we have considered above.
Turning on the sound card in BIOS
If in the system settings, everything is in order, and there is no sound anyway, then we move deeper into the BIOS parameters. Sound card can be disabled.
Restart a laptop.
Click on the BIOS input key (usually delete) until it starts.
Go to the Advanced section.
We find the High Deffinition Audio parameter and set it the value enabled.
To change the value of the parameter, go to it using the arrows and click on ENTER. The main complexity is to find a suitable option. We reviewed only one option, and a lot of BIOS versions. For example, on some Lenovo and HP laptop models, the sound card can be enabled in the Integrated Peripherals section in the High Definition Audio or Onboard Audio Chip option.
Problems with sound card or laptop connectors
If the BIOS is, too, everything is in order, then we may have encountered the most unpleasant problems - physical damage to sound card, speakers or connectors to connect external playback devices. What could happen with a laptop:
A breakdown of sound card due to fluid contact, mechanical exposure, electricity drop and other negative factors.
The failure of the service contact in the 3.5 mm connector. It can transmit a signal to connect the external device (headphones or columns), although in fact it is not.
Diagnose and eliminate these malfunctions at home is difficult, so we will offer only one proven solution - contact the service center. If you are sure that the sound card breakage is to blame, then as a temporary solution, you can try to connect an outer sound card. It is connected to the USB connector. The cost of such a device is from 300 rubles. But it is necessary to buy it only if there is no doubt about the breakdown of the built-in sound card.

The problem of playing sound files may occur regardless of which model the device, and which software is installed. This does not mean that it will take to contact the service center to eliminate the malfunction. In some cases return the sound on a laptop It turns out on your own.
One of the reasons may be the fact that the device was turned on for a long period of time, and instead of shutting down it was translated into sleep mode. Such operation leads to a failure in the program. Then the problem is solved by rebooting.
Restarting the system will help in the event that malfunctions arose not because of the violation of the rules of use, but for another reason.
Random push buttons
You can adjust the volume using the keyboard:
There is a special key accompanied by a pattern of crossed speaker. It allows you to turn off or restore sound on a laptop With one touch.
FN button, which is located on the left of Ctrl. It works in combination with the F6 or F8 key.
In order to adjust the volume, use Fn and image keys:
Dynamics and sound waves on an increase or decrease;
Dynamics, next to which the "Plus" or "minus" icon is worth;
Arrows pointing up and down.
There are devices that the audio panel is removed separately and works without the Fn button.
Information on which combinations are responsible for the volume on the laptop can be found in the help (F1 key).
Software turning off volume
Root cause Sound on a laptop There may be a computer settings. The taskbar next to the clock opens the slider, with which the sound level adjusts. Pressing the speaker icon with the right button allows you to open other functions, among which is the volume mixer. It is needed in order to set the volume boundaries in the applications. This is convenient to use in cases where you need to turn off the sound not on the entire computer, but, for example, only in the browser.
Another function is "troubleshooting sound problems." By clicking on this option, the Windows Master is launched, the task of which is to detect and correct playback failures.
It is worth considering the fact that the laptop is not equipped with powerful speakers. Therefore, the volume of the device may be insufficient to meet the needs of the user. Manufacturers went to such a step, because otherwise the device would be harder that would cause inconvenience.
However, software developers took care that this issue be resolved using programs that allow you to increase the sound without connecting speakers:
FXsound Enhancer. This free program allows not only to increase the volume level, but also is equipped with functions of enhancement bass and eliminate "quiet" sounds. Suitable for speakers, and for headphones, compatible with popular multimedia players. To use this tool, you need to start the application and click "Power" to activate the audio improvements that are removed from applications and sites.
VOLUME 2. The ability to configure the sound control panel. Available sound control functions and keyboard. At the same time, the program leaves the freedom to independently determine the key combinations. Unlike the system menu, it provides the speed settings and sensitivity of the changes, the timetable of switching volume, etc.
AudioreToucher. A simple and understandable application that allows you to adjust the parameters of the equalizer: the intensity of the sound, bass, playback speed, pace, high frequencies. With it, you can download files and correct errors in them. This program stops the selection of novice users, as it provides stability and usability.
SRS Audio Essentials. It is suitable for those who do not use Windows Media Player, as the latter also uses SRS technology. However, the use of SRS AE in combination with other players gives a positive result in the improvement of sound.
DFX Audio Enhancer. For non-commercial purposes available for free. You can configure 5 sound parameters. After installation, it will appear among notifications on the taskbar.
Sound Normalizer. Includes an audio player that supports MP3, WAV, FLAC, OGG, APE formats. You can edit ID3 tags, configure both audio channels. The advantage of the program is the file conversion function and save tags when processing information.
Invalid reproduction device
If the laptop does not reproduce the sound through the speakers, it may mean that the wrong device is selected.
See where the sound is displayed, in two ways:
Open menu on the taskbar by right-clicking on the speaker icon and selecting the "Playl Device" option.
Go to "Settings" / "Equipment and Sound" / "Sound".
Speakers must be selected (marked with a green check mark). You can turn on their left-click or by pressing the right key and selecting "Use by default".
The error occurs due to the fact that there are HDMI output on some video cards, and the sound is displayed there. Such changes in the settings occur when the laptop is connected to the monitor or TV. Therefore, you need to check the installation of the device's sound card and make sure that the playback function is turned on on it. You can see it in the device manager, in the Sound, Video and Gaming Devices tab.
Problems with driver
If an exclamation mark or a cross appears next to the audio card icon in the controller, this means that the problem is in the driver. Attention should notice whether the "Unknown" or "other devices" does not appear, in which such problems will also be displayed. To restore sound on a laptop You need to reinstall them.
Causes of failure can be that the system recently changed the system or its components. Windows 7, updated on Windows 10, does not guarantee that the drivers are not affected, since not all of them are compatible. In these versions.
Updating Drivers Set
A common options for updating drivers - right-click on a sound card and run the "Update Drivers" process. However, there is no confidence that this method will eliminate the problem and solve the question of sound reproduction. It is safer to take advantage of a special program that allows you to analyze which components are needed, checking compatibility and load them.
List of update programs:
Driver Pack Solution. A free version is available on the official website, where the user is provided with instructions. It is suitable for those who do not want to delve into all the subtleties of the software, since this application has a clear and simple interface. Works with new versions, so the client does not need to worry that its equipment will contain outdated components. The set of options includes antivirus.
Driver Booster. One of the most used programs. Exists in two versions. Free makes it possible to quickly find the desired driver and download it. Paid does not set download limits and allows you to adjust the application settings. By paying, the buyer receives the program updates automatically.
Driverhub. Although it contains less functions, gained popularity due to ease of use and speed. Saves the history of downloads and updates, you can set the recovery points if a failure occurs after the update.
Slim Drivers. This program allows you to manage processes manually controlling every moment. The paid version can be installed on 5 PCs, however, it requires special knowledge, which is a difficulty for inexperienced computer. Free version does not contain a large number of advertising, unlike other applications.
Another reason why not Works sound on a laptop may be improper configuration of the BIOS. This is a basic system that provides OS access to laptop equipment. She takes control over after switching on and checks all programs and components.
To enter the BIOS, you need to act quickly, in the first seconds when you enable the computer. What key or the combination is pressed depends on the model. It can be delete or f2. Input information is displayed at the bottom of the screen when the laptop is loaded.
A number of manufacturers blocks input for battery devices. In this case, you need to go by connecting the laptop to the power grid.
There is no single instruction how to find the item in the system, since there is no single name and partition where sound settings are. Looking for options, in the title of which are the words Audio, Azalia, AC97, SOUND.
After the function is found, it is transferred to "Enabled" mode (Enabled, Auto). Installations retain the F10 key. To exit the system, press Escape.
If the problem was in the BIOS, then after rebooting, the sound will appear.
Problems with the connector
Sometimes the sound disappears when the headphones or columns are connected. Before drawing the findings that the problem in them, you need to try to connect them to another PC or TV to understand whether they work.
The reason can be:
Incorrectly selected connector (there is a headroom and audio output);
Connector malfunction, which is not provided with a tight entry of the plug (occurs with frequent use): the oxidation of the contacts, a short circuit, discharged socket;
Headphones are connected to standard output;
The 3.5 mm socket is not marked in the settings as the default device and the PC does not see it, as a result - No sound on a laptop .
In the latter case, you need to determine the type of headphones. They differ in the number of contacts on the plugs: 4 on the headset and 3 - on standard. If it turned out that the reason for this, you need to use the adapter, and the playback problem will be solved.
The adapter contains two outputs: red (for microphone) and green (standard color for connecting equipment for audio play).
In some cases, you will have to disassemble the system unit and check if the jack for external devices on the motherboard is connected. For such work it is not recommended to take, if there is no knowledge and skills in this area. You need to charge the computer master and then when you need to replace the connector due to its mechanical damage.
System service failure
Updates of the system or its components can cause program malfunctions. If this happened, you need to return to that version at which the audio services worked.
To do this, in the Start menu, you need to select "Programs" / "Service" / "Standard" / "Restore System" / "Restore the earlier state of the computer".
Points of recovery and their dates will be offered. After selecting the desired point, the computer will restart independently and return to the previous version.
Question from the user
Not so long ago, on my laptop, Windows 7 was updated to 10-ki and I now disappeared the sound. The drivers seem to have installed, the volume icon without cross, everything is fine with him, the sound added to completely. I don't care ...
By the way, everything else (with the exception of sound) works well. Tell me at least to dig in which way?
If the sound disappears when Windows is reinstalled - in the overwhelming majority of cases, there is no driver here (it may be "crooked" and it is required to delete it, and the new installation), or the playback device is incorrectly selected in the OS sound settings.
In this note, I will give not only the solution of these reasons, but also several other (most popular and frequently found).
Why there is no sound on a laptop: the main causes and decision
By the way, if you have not installed anything and have not been updated, and the sound just lost suddenly - try primarily Reload Laptop .
It often helps (especially in cases where users do not turn off their laptop completely, sending it always to sleep ...).
Next I recommend right-clicking on the sound icon in the tray (next to the clock) and open Mixer Volume (Also, it can be done 👉 in the Windows control panel).
It allows you to adjust the volume in various applications separately from each other (for example, if you do not have sound in the browser, and in games there is it quite possible that the "is to blame" the volume mixer).
What to do, if Volume icon does not react or disappeared in general - See Instruction
Open Volume Mixer (Windows 10)
Pay attention to the slider responsible for the volume opposite each application. Check that the speaker volume is not reduced to a minimum ...
Check the speaker volume (Windows 10)
By the way , Windows often happens another unpleasant moment - the system is not always Correctly selects the device Through which the sound should be played.
Moreover, sometimes the sound can be applied at all on a non-connected device! In this case, in the usual dynamics of the laptop or the headphones conjugate with him - there will be no sound ...
To check this time, open the control panel and go to the tab. "Equipment and Sound / Sound" .
How to open a control panel in Windows - See Instruction
Equipment and Sound - Sound
Next, check whether you have chosen correctly Device by default To play sound (on it, the green tick is on).
Try to select another device if the sound does not appear - check everything alternately.
Default playback device
If you recently reinstalled the system, for example, updated Windows 7 on Windows 10, changed some components, something connected - in this case, the absence of sound is certainly related to Drivers .
Drivers from the same Windows 7 are far from always fit to Windows 10 (at least a new system and trying to install the driver for each connected device - it does not always do it).
And so, to check and update the drivers, I recommend open 👉 Device Manager.
To do this : Press the combination Win + R. , Enter the command Devmgmt.msc. In a string "Open" and click OK.
Launch Device Manager - Devmgmt.msc
In the Device Manager, you must disclose the tab. "Sound, game and video devices" (Other devices ", if you have it) and see if there are devices with exclamation marks.
Next, right-click on your audio map (Usually, its name is something like "REALTEK HIGH DEFINITION AUDIO") and in the context menu that appears, specify the option "Update Drivers" .
Update audio driver
As an example - there is no driver for this device
but I note that this way is not always possible to update the drivers. In this case, I would recommend additionally to run the system with the help of specials. utilities (they can automatically find and upload all the necessary drivers and system components that are missing in your Windows OS).
For example, such a utility, as the DRIVER Booster, not only can update the drivers, but also to carry out a full-fledged Diagnosis of reasons There is no sound (in some cases it is possible to quickly restore the laptop operation).

Audio Driver Settings
In the overwhelming majority of cases, the updated audio driver in the system has Its control panel . Those. In addition to the task of some volume parameters in Windows - in this panel your settings that can directly affect volume и quality Sound.
To open the audio driver settings - usually enough to go to the Windows Control Panel to the section "Equipment and Sound" .

In my case, this is the panel from "B & O - Play Audio Control" (In your maybe another, for example, any dispatcher "Realtek HD ...", "Smart Audio", "Dolby Digital Plus", etc.).
B & O - Play Audio Control
RealTek Dispatcher - Additional Loudspeakers
Dolby Digital Plus - Music Setup
In general, a way there is - check that the sound in the audio driver parameters is turned on and the output to the desired playback device.
Sound is disabled in BIOS / UEFI
If anyone knows, then the BIOS (UEFI) is a set of micro programs that provides Windows access to the iron of your laptop. As a rule, the BIOS settings allow you to disable some devices: the Bluetooth adapter, audio and video card, CD-ROM, etc.
In general, usually, if you yourself did not change the BIOS settings - spontaneously they do not disable various devices (it is possible if you got a battery on your motherboard - they could drop ...).
As a rule, the audio card settings (if there are in your version of the BIOS) are located in the section "Advanced" . For example, in the ASUS laptop for it corresponds to the parameter "HD Audio Controller" . Check that it is turned on (Enabled mode).
How to enter the BIOS (UEFI) on a computer or laptop - https://ocomp.info/kak-voyti-v-bios.html.
Audio Controller - Enabled (enabled)
In general, if you do not know if you have an option (responsible for switching on / off an audio card) - you can simply download Optimal BIOS settings (with them all laptop components will be included).
To perform this operation, it is enough to go to the section "SAVE & EXIT" and click on item "Optimized Defaults" (Usually, the F9 button). After saving settings and restart the laptop (button F10).

Windows Audio is disabled
Service is responsible for the sound Windows Audio. . In some cases (with system failures, infection with some viruses, etc.), its work can be broken. It is recommended to check whether it is done at all ...
To invoke the services window - you must press the combination of buttons Win + R. , in the string that appears "Open" Enter the command Services.msc. And click OK. See Example below (👇).
Open service - Services.msc (universal method)
Next, among the list of services you need to find "Windows Audio" , open it and see the condition (ideally there must be "Performed" ).
Also pay attention to the startup type - by default it should be automatic .
By the way , Try manually stop the Windows Audio service, and then run again.
Verification of Windows Audio / Clickable
If there is no sound in headphones ...
If there is no sound from the speakers of the laptop, and when the headphones are connected, it is not - the following reasons are very likely:
Windows incorrectly selects the playback device (try to enter the sound settings and manually specify the headphones as the default device - how to make it specified at the beginning of the article 👆);
You connect headset Headphones K. ordinary audio output (note the photo below 👇);
Laptop audio and output fault (with frequently connected / disconnecting headphones, the connector could start a left and not ensure a dense connection);

Excellent software to create their first videos (all actions go along the steps!). Video will make even newcomer!
A program for cleaning Windows from "garbage" (deletes temporary files, speeds up the system, optimizes the registry).
If you have a sound on your computer, it is certainly very bad, you need to figure it out as soon as possible why it happened and solve this problem quickly.
The reasons for the sudden absence of sound can be very different, it can be anything that you can consider the 10 most popular reasons. They will fit almost under any windows, from XP to 10, including Windows 7 and 8.
I will immediately ask you, please do not hurry before writing in the comments say what to do, I do not have sound on the computer, there is nothing to help. At first, consider and work all 10 steps, I am confident by 99 percent that the devil lies in one of the resulting causes.
What to do if sound disappeared
Let's start as usual with a simpler, graduate difficult.
1. Volume controls
Pay attention to the volume icon in the notification area and click on it.
Naturally, the volume slider should stand at least in the middle. Make sure that it is not at the bottom.
Well, if the volume icon has this forbidden icon, it means that the sound in the system is completely disabled.
Click on it and the sound will appear again.
Next, click the Volume icon with the right mouse button and go to it. Open the volume mixer.
Here we should also have everything included.
If suddenly some of the sliders at the bottom, then move it at least to the middle and then the sound from the speakers will appear.
Do not forget to check the sound on the speakers, make sure that the headphones are not inserted into them if they are there, then you need to pull them with you.
2. Playback devices
And so continue to seek the answer to the question why sound sounded on the computer.
You need to go to those devices that differ and check.
Click the volume icon and go to Playback devices .
In the program that opens, we find your speakers in the device lists and check that the green tick stood there.
If you do not give her no, then you need to click on the device with the right mouse button and choose the item Use defaults.
If you have speakers are highlighted with gray, and the status is worth Disabled That fix it is easy. Press the right mouse button and select item Enable naturally Do not forget to make them by default.
It happens that there are no our speakers at all, they are not displayed, in this case, you need to click on an empty place and choose Show disabled devices. The speakers after that will appear and they can be turned on as I wrote above, and then make the default.
3. Check the sound card
You need to be sure that the sound card is enabled if there is still no sound in the speakers, then this moment should also be checked.
Click on the computer shortcut right-click and open Properties.
Left Go to Device Manager.
We need to find sound devices.
Inside sound devices Turn on Your audio card, if suddenly it is disabled.
It may have already been incorporated, or maybe there is no such thing here, there are different cases, if your sound card is not displayed, but there is a section of other devices, for example, an audio device on the tire, and near the yellow exclamation mark.
This means that the driver flew and needs to be re-installed. I'll tell you about this in the next point.
4. Check the driver to sound (important!)
If you suddenly determined that the sound you have disappeared on your computer because of the lack of driver, then you need to naturally set it again.
But for those who have this driver, I still advise you to install, since most likely the previous version has already been outdated and it will be updated more fresh.
To begin with, we define which driver to download.
Let's go back to the Device Manager and press twice the sound card.
Click the tab intelligence, Find section Properties and select from the list ID equipment And a few values will appear for us first need the first. Copy it.
Next, we go to the site Devid.info, in the search string, we drive this value and click Search.
This site will select the most appropriate driver for us and we will remain to download the latest version under your operating system.
After downloading the driver, run the installation file if it is available.
If the driver was downloaded in some other format, it is installed a little differently you need through the task manager, to click the Driver tabs Refresh.
After that, search for drivers using the built-in program.
Click the review and specify the path where the driver lies. Click Next.
The installation will be executed at the end of the driver version to be updated.
But installing the driver to sound is not all.
For those who have a sound card Realtek. And it costs almost everyone, I recommend installing an auxiliary program.
It is called REALTEKHIGH DEFEnder Audio Driver. It helps a lot when working with sound. If you admire the sound on the computer, again after installing Realtek High Defender Audio, the problem with the high probability may decide.
Download Realtek and install.
Installation passes in two stages, first the program copies the necessary files and warns that the computer will be rebooted, and after rebooting the driver fully continues its installation.
Upon completion of the installation, the computer will again need to restart so that all changes entered into force.
As a result, we will see a new icon next to the volume regulator, it is a small column that says that the program is already working.
It can be launched and you can even perform some settings but about this in the next article.
5. Connect to a computer
If the sound has not yet earned, then here you have another reason, it is occurring from time to time. Here is his way to solve.
Expand the system unit and check the cable from the speakers completely inserted into the appropriate connector.
It is almost always highlighted by a green color, this is a connector for columns. Check the cable is tightly inserted into this connector. And in general, for reinsurance, I advise you to pull it out again and insert again.
6. Windows Audio
Sometimes it happens that the sound disappears due to service failure. Let's check that everything is in order there.
To quickly open services, press the Windows + R Hot Keys.
Enter the command in the string Services.msc.
In the services you need to find Windows Audio, I go down the little below we find and see in paragraph state, This service worked.
If suddenly it does not work, then click on it right-click and open Properties.
Select the start type automatically, Click apply Run и OK .
After that, it is desirable Reboot Computer and check the sound. If he did not earn, then we go further, I still have four possible reasons.
7. Verification of speakers
Of course you have already been checked 100, turned the volume regulators on the speakers, but I can't miss this item, as it happens that somewhere the postings departed, the speakers forgot to insert. Or allow headphones broke and the like. And the user immediately rushes to panic, what to do, there is no sound, which happened.
Connect the speakers in which sound disappeared to another computer or laptop. So it will be much more reliable if you do this procedure, then you will be 100% sure that your columns are not broken, it will be much easier. The same goes and headphones, if there is no sound there too.
8. Sound setting in BIOS
This step for those who recently produced some changes in the BIOS. If you are in BIOS, something changed, that is, the probability that you accidentally disconnected the function that is responsible for the sound.
Restart the computer and go to the BIOS.
Usually on the advanced deposit you need to find item High Deffinition Audio. where the sound should be in mode Enabled If suddenly disabled, then change. After that, we save the changes using the F10 key.
If you have some kind of hard virus, then it is 100% what he hurt our computer.
You need to remove all malicious programs. Well, of course, due to viruses, the sound rarely disappears, but it also happens, so this step needs to work
10. Restoring the system or reinstalling Windows.
If you suddenly disappeared sound on a computer or laptop, and you even know what day it happened or after which operation, you can return everything to the system rollback.
There is such a cool chip as the restoration of the system. Below the instruction as you can run.
Open Start and in the search bar drive Restoration of systems.
Run the program found.
We can immediately recommend to roll back the latest changes.
But if you know the exact date when the sound disappears, it is better to choose the item Select another recovery point.
In the next step, you need to specify the date on which the computer will be restored. Click Next.
We specify the disk and click ready.
The computer will restart and rollback will be performed in the change system.
And in the saddest cases, when the system recovery did not help or was completely disabled, then you can help reinstall Windows. It seems to me the latest attempt to return the sound on the computer
I hope you carefully worked all 10 steps before you reached this moment.
Well, if you suddenly you immediately decided to watch this moment, what to do if nothing helps, I strongly recommend Check the sound card ,Audio service , Install Driver or update it Restore the system etc. Already after read further.
But if you did all this, and it does not help you, it remains only to attribute the computer to the master and let him look at you. Most likely you broke the sound card and you will need to replace it.
In any case, I ask you to write in the comments, as you managed to solve the problem with the sound on your computer. Wish you luck.
Not the most pleasant situation, it is not possible to find that there is no sound on a laptop, how to recover - the question that will have to decide in stages. There are several reasons why the sound on the laptop is not reproduced (not included) - both software and technical - and the diagnosis at home is organized by the exclusion method.
Possible causes of lack of sound: How to check and restore?
How to make sound on a laptop if it does not work - a problem, the solution of which is worth starting with volume controls. In the laptops, the volume is adjusted not only by the click of the mouse, but also with the help of hot buttons on the keyboard, therefore, perhaps the slider "Dynamics" Founded in position "MUTE" (silently). To adjust the volume, you will need:
On the taskbar, find the horn icon. By clicking on it right mouse button (PKM), the user will see a menu in which you need to choose "Mixer" .
Check the position of the slider - if necessary, shift the regulators.
Tip: If there are no problems with the headphone connector, then you should use it to check at each stage. You need to enable any sound file and insert headphones into the connector. If the song will sound during the next setting, then you can remove them from the connector.
Situations occur when the speakers do not work on a laptop (there is sound in headphones); What to do is a question for the repair master, because it is a technical malfunction of the speakers.
If suddenly you do not know how to connect headphones to a laptop, then we will tell you about it in our separate article! Read and ask your questions!
The question is how to enable speakers in a laptop if there is no sound, it may occur in situations where the user added a device in the settings - columns (both wired and wireless) or audio systems. To restore the operation of the speakers, you will need:
Click PCM again on the horn icon, but to choose another item.
Open tab "Reproduction" . If a "Dynamics" disabled, then you need to restore their work - click PKM and choose "Enable" .
Why there is no sound in the laptop (all volume controls are included) - a frequent question, because the main source of problems are the driver. To restore their work, you will need:
Take advantage "Device Manager" . You can find it using "Control Panels" Or search string.
Release the list of audio devices. By clicking on the PCM on any of the drivers, you can open the menu. Using this menu, you need to update the drivers.
If there is no need to update, then you should choose in the same menu "Stop" , and then "Enable" For each installed driver.
After the user restored the operation of the drivers, the laptop reboot will be required.
If you still failed to solve the problem: "Why the sound on a laptop does not work, what to do" (Windows 7, 8 and 10), then you should check the Windows Audio service. To restore the service, it will take:
Click on the keyboard at the same time "Win" (Windows icon) and "R" . Enter in the field "Services.msc" and click "OK" .
Find in the list Windows Audio. and click PKM. Select in the menu "Run" if the service is disabled, or "Restart" - If the service works.
The next level of the problem is why sound in a laptop how to fix, if there is no sound at all - it's worth trying to solve through the service "Troubleshooting" . This will require:
Click the PCM on the horn icon on the taskbar.
In the Select menu "Troubleshooting" .
Follow the service prompts to restore the working audio settings.
As a rule, after that it will be necessary to restart the laptop.
If the problem has reached the level "why there is no sound on a laptop, what to do, although everything is turned on and works," then two options remain - a disabled sound card (in the BIOS) or a technical malfunction. Possible breakdowns:
The speaker is broken - sounding only in headphones.
The sound fee is broken - there is no sound support or it is distorted.
Problems with speaker contacts - sound support arbitrarily appears and disappears.
You can restore the operation of the sound card in BIOS yourself (but neatly and carefully, to not break the laptop at all), and the other problems must solve the repair master.
