Hello friends. If, after installation, there are problems with the sound on the computer, that is, it completely disappeared or it is not only in the headphones or is not played in games, then the reason lies in the fact that the sound drivers have not been installed. It is difficult to say why this is happening, I had no problems with this, only with, but the drivers for the video card did not get up. Now let's see what can be done about it and how to fix the situation.
Lost sound in Windows 10. What to do
Before we dive into the wilds, let's see Windows 10 sound settings may just need to increase the speaker volume. And even if the 5.1 sound does not transmit via HDMI. First, click on the speaker icon in the tray (bottom right) right click mouse and select the item: Detect problems with sound. 
If the troubleshooting module has identified the cause, then it will write what the problem is. But most likely the audio service is not running or the drivers for the sound card are not installed. Then it will be clear in which direction to move. If nothing was found, then open Playback devices. Click 2 times on Speakers.
We need the Levels tab. We check if all the sliders are at the proper level.
By the way, Realtek High Definition Audio in Windows 10 is installed automatically with all updates. Let's go to Start - Settings - Update & Security and looking for updates. If it finds something, it will be clear what it is. You may need to restart the computer, during which all the necessary updates will be installed, and with them the drivers.
Windows 10 sound drivers
If nothing helped and the sound still does not work on the computer, then let's check if the audio drivers are installed. It doesn't matter which one is in the case, Asus or some other, if you think that they need to be downloaded, then no, we will use the automatic search for drivers.
They are not on the official site, but from others, it is extremely unsafe to download them.
Next to Start there is a search button, click on it and write: Device Manager. We select it. We are interested in Sound, game and video devices. Expand the list and if there is nothing there, right-click and select: Update hardware configuration. If there is something, then click update drivers. We do the same where: Audio inputs and audio outputs. 
After the done manipulations, everything should work normally and without failures. Those of you who have updated Windows 8.1 or Windows 7 to version 10 and you have lost the sound, then write in the comments whether my instructions helped you or not. If so, feel free to share this post on in social networks. Here
Imagine the situation: you turn on your computer, speakers, look forward to watching a new movie and suddenly it turns out: after the update, the windows sound 10. At least it will upset. And if you have important negotiations ahead of you or watching a live broadcast of the semi-finals of the World Cup? Almost a disaster. We will tell you what can be done if after windows updates 10 sound problems appeared.
The easiest
First, check the operation of the speakers and headphones. You can try to adapt external devices to another PC or gadget. Inspect all wires, make sure the plugs fit snugly into the ports.
If the equipment is in good condition, use the system service. Hover your mouse over the tray speakers icon and right-click.
Wait until the end of the diagnosis and read the recommendations.
Follow the steps that were suggested to you to solve the problem when the volume disappeared. In our case, let's try to disable all sound effects. This can help when there is a quiet sound after windows updates 10. And what to do if - follow the link and read detailed instructions on solving this problem.
Verify that the correct devices are listed as active.
Go to the "Sounds" section by right-clicking on the mixer icon.
On the tab "Playback" select the required equipment.
Reinstalling drivers
If visible reasons missing, but after updating Windows 10 the sound does not work, we are looking for problems in the drivers. They will be found in device manager(right click on the main button).
In the audio hardware section, you should see the normal name of the hardware.
If you only see the device type and signature "Device with High Definition Audio", this is an indicator that during the update the system could not determine the model and manufacturer, and universal drivers that do not work with your devices. And as a result, the audio accompaniment disappeared.
You need to download the correct "firewood". Look for them in search engine. Enter the name of the laptop or motherboard and the word "support".
Follow the link and act according to the requirements of the site. For Lenovo, for example, you need to specify serial number or complete model. After that, a list will be issued software. Look for the right one. If you have not yet installed Windows 10 OS, then we advise you to enable .
Attention! Not necessarily the drivers will be written specifically for Windows 10. If they are not there, don't worry, download the latest version. Check if the bit depth matches: 32 or 64.
Download and install. Check if nothing has changed and the audio signal has disappeared, you should run the installation in compatibility mode with the system for which the drivers are written.
- Open the folder with the executable file and call the properties window.
2. Panel "Compatibility" click the checkbox and select the appropriate OS version.
3. Apply the changes and run the file again.
If everything remains unchanged and the situation when there is no sound after the Windows 10 update (suddenly disappeared) remains, do the following:
- Go to task manager.
- Remove from partitions "Audio inputs and outputs" and "Sound, game and video devices" all devices marked as unidentified.
3. Run the installation compatible with older OSes again.
Especially often this method of solving the problem when the sound disappeared after updating the drivers on Windows 10 helps with Realtek devices.
Lowering the volume
When, after updating Windows 10, the sound became quieter or the volume gradually disappeared by itself, in the properties window, go to the "Communication" panel.
Click "No action required".
An inscription appeared on the screen, you will learn what to do and how to remove the inscription forever in another article on the site.
And the last reason why, after updating Windows 10, the sound does not work well or the sound has completely disappeared - disabling the Windows Audio service.
- Press WIN+R and type in services.msc .
2. The Microsoft Services window will appear. Scroll to the desired line and make sure everything is enabled.
We hope this information helps you!

- 2. Sound not working after Windows 10 update
- 3. Quiet sound, wheezing or automatic volume reduction
- 4. No sound in games
- 5. Conclusion
To date great amount users have already encountered a lot of various problems after the update operating system before Windows versions 10, and perhaps the most popular software flaw was the lack of sound on personal computer under the new OS.
Although the “top ten” has been out for a relatively long time, nevertheless, many users are still driving into search string the phrase “Windows 10 no sound”, which means that our material today can be very useful for you.
Reasons for loss of sound
There are not so many potential sources of this problem, and therefore each owner of a new operating system is able to independently identify the root of the trouble. We remind you, no matter how ridiculous it may sound, that the most common cause no sound are unconnected speakers, so be sure to check the working condition of the devices that output sound on your PC. It is also common that the owner of the computer or someone in the household turned off the sound and simply forgot to return the settings to the initial state, and therefore be sure to check the status of the volume icon in the panel quick access. 
Another potential technical cause of trouble is a damaged speaker cable, before blaming everything on software problems, try testing the device on another PC or other sound source. If you have no sound in the headphones, then it is also recommended that you first try them on another gadget. 
As for the software component, here it is worth starting a system check with sound driver, it may be defective or outdated. You can update the “firewood” on the website of your sound card manufacturer, but we strongly do not recommend using third-party resources, otherwise, when solving problems with sound in Windows 10, you run the risk of acquiring a lot of new ones caused by picked up malware.
By the way, you can easily avoid searching for suitable drivers by simply selecting all the items in the control panel menu “Sound, game and video devices” and calling the context menu by clicking the right mouse button, in which you need to activate the hardware configuration update function.
Sound not working after Windows 10 update
In the most common case, after updating the OC, the speaker icon does not display any problems, in the task manager, opposite the sound card, the status is “The device is working properly”, and the driver does not need to be updated.
In order not to proceed prematurely in such a situation to search for another answer to the question of why the sound on the computer disappeared after Windows installation 10, take a close look at the name of the sound card in the device manager, if the design “High Definition Audio capable device” is displayed there, then you can be sure that the problem is in the drivers. Most often, this problem occurs with Conexant SmartAudio HD, Realtek, VIA HD Audio sound cards. Also, if you lost sound on Sony laptop or Asus, then the problem should be looked for first of all here. 
The algorithm of actions to correct the current situation is as follows:
- Enter the name of your laptop model in the search box or motherboard and add the word support at the top search results there should be a device manufacturer's website where you can update the driver you are interested in.
- We find the drivers we need in the support section, if there is no suitable software specifically for Windows 10, then this does not matter - firewood for a seven or eight will suit us, the main thing is that the bit depth of the system matches.
- Install the downloaded drivers and reboot the PC, after that the sound should work.
A common situation is when the user has traveled this path, but a positive result has not been obtained, as a rule, this is the result of incorrect installation of the software, and the driver installer does not report this. Check in the manager if the information about the driver has changed after installation, and if not, then follow the following instructions: 
- In most cases, running the installer in compatibility mode with the previous version of the operating system will help you;
- If the first option did not help, then you should try to remove the sound card in the manager, as well as devices from the list of “audio inputs and audio outputs”, preferably together with the drivers, and immediately after that run the installer;
- If installed old driver, then click on sound card right-click, select "Update driver" - "Search for drivers on this computer" and check if there are already in the list installed drivers new compatible drivers for your sound card.
Quiet sound, wheezing, or automatic volume reduction
Sometimes there is sound, but its quality leaves much to be desired. In such a situation, you need to configure the sound on a computer with Windows 10, which is done as follows: 
- We click on the speaker icon in the quick access panel with the right mouse button and go to playback devices;
- We select the device with which there are problems - speakers or headphones, after which we right-click on its properties;
- In the tab additional features turn off all effects and apply the updated settings;
- Now open the Communication tab and uncheck the box to reduce the volume or mute the sound during communication, selecting the “No action required” item.
After applying all the settings, it’s worth checking the status of our problem with sound not working on Windows 10. Most likely it is solved, but if not, try again to turn to the drivers and install not the native driver for your board, but one of those that the operating system itself will offer system. Often, third-party drivers can restore high-quality sound.
No sound in games
If the game process does not have sound, then you need to answer the question of how to set up sound in the application itself. As a rule, the menu item responsible for sound settings is not difficult to find, but if the sound disappeared after updating the operating system, you may need to manually reinstall the game. In this case, don't forget to copy all saved progress before deleting the app. 
Conclusion
As you can see, there are not so many reasons why the sound stopped working - these are technical flaws in devices or connecting cords, user inattention, or software problems caused by driver mismatches or their absence. Dealing with any of them is quite simple, you just need to follow the instructions clearly and check whether software update it was found.
In the event that no defects were found on the output devices, and the drivers are in order, there is a small probability of a malfunction of a particular sound chip or problems with its interaction with motherboard in which case we recommend that you contact service center if you do not have proper experience in working with microelectronic boards. We hope that our material helped you solve the problem and your PC again pleases you with your favorite music or soundtrack.
Here I want to talk about easy way fix sound problems on Windows 10. This method is simple and can work in any situation, follow all the steps very carefully so that there are no questions later. The problem often occurs when upgrading from Windows 8.1 to Windows 10, or due to a failed driver update. I had this, and I fixed the situation in the way described in this article, but not the fact that it will help you too.
If the sound does not work on Windows 10
Stage 1:
We launch the device manager. To do this, you must right-click on the Start menu and find it there. It is also possible to do this: press the Win + R keys and enter the command devmgmt.msc .
Stage 2:
Find the tab in Device Manager "Sound, game and video devices". There are sound drivers.
Stage 3:
Right-click on the sound device and select the item "Update Driver".
Stage 4:
Click on a section "Searching for drivers on this computer".
Stage 5:
We find ourselves in a window where you need to click on the option "Select a driver from the list of already installed".
Stage 6:
Find the latest sound driver and click on the button "Further".
Let's go back to step 4. Here you can choose automatic search drivers over the internet. Then, perhaps, a message will be displayed that it is installed latest version drivers. If you click the "Search for drivers on this computer" item again, and then select the path to the driver file, this may well solve the problem.
Alternatively, you can uninstall the sound driver, then restart your computer or laptop, after which it will automatically be reinstalled.
- I advise you to read about the causes of sound problems:
- About sound cards:
In short, if there is no sound on a Windows 10 computer, this method can help, but not always. Then I will write a couple more articles on correcting errors with sound. Also, offer your solutions and talk about the errors that you have, and I will try to solve them.
What to do if there is no sound on your windows 10? Firstly, do not despair and do not blame the manufacturer of acoustic equipment and expansion cards of the same name that are in the car.
If for no reason the broadcast disappeared after reinstallation or for some other, absolutely unknown reason, there can be two sources: drivers and force majeure.
Driver Issues
See what is being used as a basis. If these are not speakers, but, for example, HDMI from a TV that is not currently connected, change the source to the main one.
If these are speakers, then select the item, click on the properties and carefully review all the tabs in this section.
Unnecessary or unknown effects should be turned off out of harm's way until the problem is resolved.
In the case of installed software from any manufacturer of cards (for Asus Xonar, for example), also carefully review all the tabs for enabling / disabling some key parameters.
Suddenly, the system switched playback to the optical output, and the speakers are powered by a banal 3.5 cable.
- Windows Audio
Open Device Manager by typing devmgmt.msc. You need a tab related to sound.
We click on it with RMB, look for properties and look at what is written in the column with the state of the device.
If everything works fine (as it is written), then use the initial instruction at the top, which says about the correct drivers after reinstallation. Download and install them.
But if something is wrong, also look towards the driver. The system often itself makes it clear what steps exactly need to be taken.
Also try administration. Go to the control panel, and find the "services" item, where you will find Windows Audio.
Look that in the "launch type" it was "automatic", and not some other item.
Connecting via BIOS
An extremely rare problem that sometimes occurs is disabling directly in the BIOS. built-in sound card may simply not work.
To solve the problem associated with this, you need to know the model of your MP, BIOS version and other parameters.
As a last resort, it's best to ask your motherboard/laptop manufacturer's support about this. They should be notified of the issue.
The most common problem is with the hardware. Most often, the wires remain in sight, which is why pets “eat” them.
Less often, the person himself touches the cable. Much more serious if the acoustics itself does not work.
No matter how strange it sounds, but it is worth smelling it to make sure that nothing is burned.
Software errors are "treated" at the level of reinstalling drivers. It is advisable to download them not from the developer's website, but from the website of the manufacturer of your MP.
If the board is separate, then find out the exact model and go to the manufacturer's resource.
Sound not working after Windows 10 update
Despite the fact that updates in Windows 10 are designed to improve the performance of the system, they do not always succeed. Sometimes, after updates, there are problems with the computer hardware. If the sound is not working after updating Windows 10, then you need to watch this video tutorial.
