In this article, I will tell you why the “Audio output device is not installed” message appears in Windows 7 and Windows 10, and how to fix it. Many PC users may notice a sudden significant decrease in or. Sometimes this happens after installing some system update, but usually the problem occurs suddenly, without any visible reasons. This dysfunction can be of both software and hardware nature.
List of reasons for sound problems
Usually, if there is no sound on the PC, we can see a sound icon (speaker) with a red circle and a cross on it on the taskbar.
In the statistical majority of cases (about 80% of all problems), the “Output audio device is not installed” problem is caused by drivers for audio devices that are either damaged, do not work correctly, or are not installed at all in the system.
In other cases, the cause of problems with sound may be various malfunctions in the Windows OS, the activity of viruses or anti virus programs, and software shutdown sound devices (in BIOS or Windows, accidentally or intentionally).
Also, do not discount hardware malfunctions, for example, a failure of a headphone (speaker) plug, a breakdown of the audio connector on the motherboard, or a malfunction of the motherboard of your PC.
Moreover, in both Windows 7 and Windows 10, the causes of the malfunction are similar, as are the methods for solving this problem.
How to fix "No audio output device installed" message
Below we will take a detailed look at the various options for solving the “Audio output device not installed” problem.
Before checking the system for correct operation of drivers and the presence of other software faults. We recommend making sure that external audio devices (headphones and speakers) are connected correctly (and tightly) to the appropriate PC connector (usually the green connector on a desktop PC).
It is also necessary to make sure that the cable and plug of these devices are not damaged, that there are no breaks or other signs of physical impact on them. It is recommended to connect them on another computer to make sure that these sound devices are working properly, and the existing sound problems are not caused by the failure of these devices.
Method number 1. Check audio enable in BIOS
In some cases, the reason for the disappearance of sound in the system is its deactivation in the BIOS. To enable sound, you need to go to the BIOS of your PC and find the “HD Audio” parameters there. Or “High Definition Audio”, or “AC’97” (usually in “Advanced” - “Onboard Devices Configuration”), select “Enable” next to them, then save the changes by pressing “F10”, and reboot your PC.
Method number 2. Solving driver problems
As we mentioned above, the vast majority of audio problems occur due to damaged, incorrect or missing drivers for audio devices. To check, you need to go to Device Manager and view there a display of the audio devices available on the PC. To do this, click on the “Start” button, enter in the search bar devmgmt.msc, and press enter.
- After opening the Device Manager window, we need to check the sound drivers in the list for problems in their operation.
- To do this, find the “Sound, game or video devices” tab in the list.
- Double-click on it, and in the list of sound devices that opens, check for yellow or red icons next to them with exclamation mark, or other symbols indicating problems with the operation of audio equipment.
If this tab does not contain information about sound devices, there is a tab in the Device Manager " Unknown device” with a question mark or “No audio output device installed,” this may indicate that the system does not have a driver for your device
What should I do if these icons are found?
- If the sound driver is disabled (sign with a down arrow), then you need to hover the cursor over this sound card, click on right key mouse, and select “Engage” in the menu that appears;
- If there is a yellow circle with an exclamation mark (or even a red one), then you need to reinstall (or roll back) the drivers for this sound device. In the first case, we recommend that you first uninstall the existing drivers. To do this, you need to hover the cursor over the sound device with the “yellow” exclamation mark, right-click, and select “Delete device.” Then restart the PC and let the system reinstall the drivers on its own, or use automatic search drivers, as indicated below.
Sound stopped working after update
If the sound previously worked normally, but after some update it stopped working, then you need to roll back the system to the previously used correct driver. To do this, hover over your audio device in Device Manager (the “Sound, Game or Video Devices” tab), right-click, and select “Roll Back” (if available).
You can also try updating the problematic driver by selecting your sound device in Device Manager, right-clicking, and selecting “Update drivers” - “Automatic search for drivers.”
Select the "Update Drivers" option to update your sound card drivers If this driver update does not produce results, I recommend using special software solutions to update drivers level " DriverPack Solution", "Driver Easy" or other analogues, or download drivers for the sound card of your PC on the manufacturer's website.
Problems in Windows 10
If you have Windows 10 installed on your PC and your sound card is displayed as a “Device that supports High Definition Audio,” this may indicate that the correct drivers are not installed for your sound card. Look for drivers specifically for your laptop (and in particular the motherboard) on the manufacturer’s website, or use the list. If you downloaded the driver installer for your sound card for another OS (Windows 7 or Windows 8), then you should try running the installer in compatibility mode for the specified OS.
If instead of the name of the sound card you see “Device supporting High Definition Audio”, then you need to install the correct driver for your system Method No. 3. Using a system tool to troubleshoot problems
A good way to solve the sound problem “Audio output device is not installed” is to use a special diagnostic manager, which allows you to get rid of various types of problems, including sound ones.
To launch it, click on the “Start” button and enter in the search bar:
msdt.exe /id AudioPlaybackDiagnostic
Method number 4. Checking the system for virus programs
In some cases, the cause of problems with audio on a PC may be the activity of virus programs. You need to get rid of them using tools such as “Dr.Web CureIt!”, “Trojan Remover”, “AdwCleaner”, “Kaspersky” Removal Tool" and others.
Method No. 5. Temporarily disable antivirus software
In some fairly rare cases, the cause of sound problems is an antivirus that blocks the correct operation of the sound device ( sound driver). To resolve this issue, it is recommended to temporarily disable the antivirus to make sure that its functionality does not interfere with the correct sound playback on your PC. If the antivirus is to blame for this problem, then it is recommended to either reinstall the antivirus or find an effective alternative.
Method number 6. Change your sound settings
Changing the bitrate of the sound card helped some users. To do this, click on the “Start” button, enter in the search bar mmsys.cp l and press enter. In the sound panel that opens, select “Speakers”, then click on “Properties”, go to the “Advanced” tab, and try switching the “Default Format” option to “16 bit, 44100 Hz”.
You can also try going to the “Additional Features” (Improvements) tab and disable all the effects involved there by unchecking them.
In the “Communication” tab, also enable the “No action required” option, this can help fix the “Audio output device not installed” error on your PC.
Method No. 7. Using a different sound card
An alternative solution to the problem is to use an external sound card connected to the computer via a USB connector. Price of this device is not high (less than $10), so we can recommend purchasing and using this device as one of the ways to solve sound problems on your PC.
Method No. 8. We check the functionality of the Windows Audio service.
In some cases, the operation of the service " Windows Audio", responsible for working with sound, may be suspended for various reasons.
- It is recommended to go to the section for working with services (click on the “Start” button, enter in the search bar services.msc, and press enter).
- Find “Windows Audio” in the list of services, double-click on it, and set the startup type to “Automatic” (if it was previously set to a different value).
- Then restart your PC.
Check the functionality of the Windows Audio service Method number 9. Using System Restore
Enough effective way The solution to the dysfunction is to roll back the system to a previous restore point, where there were no problems with sound.
- To do this, click on the “Start” button, enter in the search bar rstrui, and press enter.
- Select a stable restore point and roll back the system to this state.
Method No. 10. Reinstalling Windows OS
A rather radical way to deal with the problem is to completely reinstall the Windows OS (for some users, only this method). However, we would not recommend resorting to complete demolition operating system as long as it is possible to use alternative methods.
In particular, as such an alternative we can recommend checking the integrity of system Windows files, why run command line as administrator and then enter:
sfc /scannow
Press enter and wait for the file verification process to complete. Then reboot your system, this will help resolve the “Audio Output Device Not Installed” error on your computer.
Conclusion
Problems with the audio output device can have many causes, ranging from driver problems to a broken audio playback device. It is recommended to use all the tips listed in the article; this will help restore normal sound operation on your PC.
Many users who upgraded to Windows 10 or after a clean installation of the OS encountered a variety of problems with the sound in the system - some simply lost sound on their laptop or computer, others - the sound through the headphone output on the front panel of the PC stopped working. Another common situation is that the sound itself becomes quieter over time.
This manual describes step by step possible ways fix the most common problems when audio playback does not work correctly or the sound simply disappears in Windows 10 after an update or installation, or simply during operation for no apparent reason. See also: , .
The most common variant of the problem is that the sound on the computer or laptop simply disappears. In this case, as a rule (let's look at this option first), the speaker icon on the taskbar is fine, the Windows 10 Device Manager for the sound card says “The device is working normally,” and the driver does not need to be updated.
True, at the same time, usually (but not always) in this case the sound card in the device manager is called “Device with High Definition Audio support” (and this is a sure sign of the absence installed drivers on her). This usually happens for Conexant SmartAudio HD, Realtek, VIA HD Audio sound chips, Sony and Asus laptops.
Installing sound drivers in Windows 10
What to do in this situation to fix the problem? The method that almost always works consists of the following simple steps:
- Enter in a search engine Your_laptop_model support, or Your_motherboard_model support. If you encounter problems discussed in this manual, I do not recommend starting to search for drivers, for example, on the Realtek website; first of all, look at the website of the manufacturer, not of the chip, but of the entire device.
- In the support section, find audio drivers to download. If they are for Windows 7 or 8, and not for Windows 10, this is normal. The main thing is that the bitness does not differ (x64 or x86 must correspond to the bitness of the system installed in currently, cm. )
- Install these drivers.
It would seem simple, but many write that they have already done this, but nothing happens or changes. Typically, this happens because even though the driver installer walks you through all the steps, the driver is not actually installed on the device (easy to check by looking at the driver properties in Device Manager). Moreover, installers from some manufacturers do not report the error.
There are the following ways to solve this problem:
Even if you couldn’t find official drivers, still try the option of removing the sound card in Device Manager and then updating the hardware configuration (point 2 above).
Sound or microphone stopped working on Asus laptop (may work for others)
I would like to separately note the solution for Asus laptops with a Via Audio sound chip; it is on them that problems most often arise with playback, as well as connecting a microphone in Windows 10. Solution:
- Go to Device Manager (right-click on Start), open “Audio inputs and outputs”
- By right-clicking on each item in the section, delete it; if there is a suggestion to delete the driver, do that too.
- Go to the “Sound, game and video devices” section, remove them in the same way (except for HDMI devices).
- Download the Via Audio driver from Asus from the official website for your model, for Windows 8.1 or 7.
- Run the driver installer in compatibility mode for Windows 8.1 or 7, preferably as Administrator.
I'll note why I point to more old version drivers: it has been noticed that in most cases VIA 6.0.11.200 is working, and not newer drivers.
Playback devices and their additional parameters
Some novice users forget to check the audio playback device settings in Windows 10, which is better to do. How exactly:
After completing the specified settings, check if the sound is working.
The sound becomes quiet, wheezing, or the volume automatically decreases
If, despite the fact that the sound is played, there are some problems with it: it wheezes, is too quiet (and the volume can change itself), try the following solutions to the problem.
Apply the settings you made and check if the problem is resolved. If not, there is another option: try using the device manager to select your sound card - properties - update the driver and install not the “native” sound card driver (show a list of installed drivers), but one of the compatible ones that Windows 10 itself can offer. In this situation, it sometimes happens that the problem does not appear on “non-native” drivers.
Additionally: check if it is enabled Windows service Audio (press Win+R, type services.msc and find the service, make sure the service is running and its startup type is set to Automatic.
Finally
If none of the above helped, I also recommend trying to use some popular driver-pack, and first check whether the devices themselves are working - headphones, speakers, microphone: it also happens that the problem with sound is not in Windows 10, but in themselves.
- 1. Reasons for loss of sound
- 2. After Windows updates 10 sound doesn't work
- 3. Quiet sound, wheezing or automatic reduction volume
- 4. No sound in games
- 5. Conclusion
Today, a huge number of users have already encountered a lot of different problems after updating the operating system to Windows versions 10, and the most popular software flaw, perhaps, was the lack of sound on personal computer running the new OS.
Although the “ten” came out a relatively long time ago, nevertheless, many users still type in search bar the phrase “Windows 10 no sound,” which means our material today may be very useful for you.
Reasons for loss of sound
There are not so many potential sources of this problem, and therefore every owner of a new operating system is able to independently identify the root of the trouble. We remind you, as funny as it may sound, the most common cause of no sound is unconnected speakers, so be sure to check the working condition of the devices that output sound on your PC. It is also a common situation when 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, so 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 another audio source. If you have no sound in your headphones, then it is also recommended to try them on another gadget first. 
As for the software component, you should start checking the system with the sound driver; it may be faulty or outdated. You can update the “firewood” on the website of the manufacturer of your sound card, but we strongly do not recommend using third-party resources, otherwise, when solving sound problems in Windows 10, you risk acquiring a lot of new ones caused by malware.
By the way, you can easily avoid searching suitable drivers simply by selecting all the items in the control panel menu “Sound, game and video devices” and calling context menu by clicking the right mouse button, in which you need to activate the hardware configuration update function.
No sound after Windows 10 update
In the most common case, after updating the OS, the speaker icon does not display any problems, the task manager next to the sound card shows the status “The device is working normally,” and the driver does not need to be updated.
So that in such a situation we do not move prematurely to search for another answer to the question why the sound on the computer disappeared after Windows installations 10, take a close look at the name of the sound card in the device manager; if the design “Device supporting High Definition Audio” is displayed there, then you can be sure that the problem is in the drivers. This problem most often occurs with Conexant SmartAudio HD, Realtek, VIA HD Audio sound cards. Also, if you have lost sound on a Sony or Asus laptop, then you should look for the problem here first. 
The algorithm of actions to correct the current situation is as follows:
- Enter the name of your laptop or motherboard model into the search bar and add the word support at the top search results There should be a website of the device manufacturer 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 it doesn’t matter - the driver for seven or eight will suit us, the main thing is that the system’s bit capacity matches.
- Install the downloaded drivers and restart the PC, after which the sound should work.
A common situation is when the user has done this path, But positive result was not received, as a rule, this is a consequence incorrect installation software, but the driver installer does not report this. Check in the manager whether the driver information has changed after installation and if not, then follow the following instructions: 
- In most cases, running the installer in compatibility mode will help you. previous version operating systems;
- If the first option does 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 along with the drivers, and immediately after that run the installer;
- If the old driver is installed, then you need to click on the sound card right click mouse, select “Update driver” - “Search for drivers on this computer” and check if new compatible drivers for your sound card appear in the list of already installed drivers.
Quiet sound, wheezing, or automatic volume reduction
Sometimes there is sound, but its quality leaves much to be desired. In such a situation, it is necessary to configure the sound on a computer with Windows 10, which is done as follows: 
- Right-click on the speaker icon in the quick access panel and go to playback devices;
- We select the device with which there are problems - speakers or headphones, and then right-click on its properties;
- In the tab additional features disable all effects and apply the updated settings;
- Now open the Communications tab and uncheck the option to reduce the volume or mute the sound during communication, selecting “No action required.”
After applying all the settings, it’s worth checking the status of our problem with sound not working on Windows 10. Most likely, it has been solved, but if not, try turning to the drivers again and installing not the native driver for your board, but one of those offered by the operating system itself 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 configure the sound in the application itself. As a rule, the menu item responsible for sound settings is not difficult to find, but if the sound disappears after updating the operating system, you may need to manually reinstall the game. In this case, be sure to copy all saved progress before deleting the application. 
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 mismatch or lack thereof. Dealing with any of them is quite simple; you just need to strictly follow the instructions and check whether software update it was found.
If no defects were found on the output devices, and the drivers are in order, there is a small probability of a malfunction of the specific sound chip or problems with its interaction with motherboard, in this 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 that arose and your PC once again pleases you with your favorite music or sound.
Hello admin! I recently installed it on my Windows computer 10, but drivers for some devices were not installed along with the operating system: video card,PCI controller, some kind MEDIA and USB Device. The Internet suggested that you need to wait a day or two and the drivers will be installed automatically, but after three days this did not happen.Now in the device manager, instead of the name of the video card, there is a Basic video adapter (Microsoft), Accordingly, the image on the monitor with a black stripe and this is due to the low screen refresh rate of 64 Hz, but you need at least 75 Hz, then the band will disappear, but the required frequency will appear only after installing the real driver on the video card.
I went to the official NVIDIA website and the drivers there are only for Windows 8.1. I downloaded the DriverPack Solution driver package, but it does not start on Windows 10, an error appears. Question to How to install drivers on Windows 10?
Hello friends! Don't forget about the built-in automatic driver search tool in Windows 10. Microsoft servers contain a very large database of drivers for almost all known devices. In today's article I will simply remind you how to use this tool, a more complete article is
After installing Windows 10, go to Device Manager and see devices (marked with a yellow triangle with an exclamation mark) for which drivers have not been installed. For example, let's expand the Video adapters item and see that the basic Microsoft driver is installed on the video card, and the drivers for sound and the motherboard chipset are also not installed.
One good thing is that the drivers were automatically installed on network adapter connections via local network and network wifi adapter and we have internet. If Windows 10 did not find a driver for your network adapter during installation, then you have no choice but to use another computer with the Internet and download the driver to network card Well, there are no drivers for Win 10 yet, but I’m sure that the driver from Win 8.1 will definitely work.
In Device Manager, right-click on the base video adapter (Microsoft) and select Update Drivers.
Click on the button Automatically search for updated drivers.
An automatic search for software for your video card occurs on the Microsoft server.
The driver has been found and is being downloaded
Installation.
Reboot the computer
And we see that the driver for the video card is installed. In exactly the same way, we install drivers on all devices with a yellow triangle and an exclamation mark.
Friends, if you won’t be able to install drivers on Windows 10, then try special ones. You can also try assembling drivers.
Free update Before Windows 10, millions of PC users took advantage of it. They were able to evaluate all the advantages and disadvantages of the new operating system, including a considerable number of errors that arose due to the incompatibility of equipment with ten, incorrect settings system, lack of necessary software. Sound was no exception in this regard. Already Windows users 10 received the update Creators Update, and will soon receive the Full Creators Update. However, the error “Sound devices are not installed on Windows 10” continues to occur. What to do in this case and how to fix it?
Ways to solve the problem when sound devices are not installed on Windows 10
If you encounter a message that no sound devices are installed and you don’t know what to do on Windows 10, we suggest that you familiarize yourself with the following recommendations.
Method number 1. Troubleshooting
If this problem appears on Windows 10 after an update or a clean installation of the operating system, you should use standard means to troubleshoot problems. To do this we do the following:
- Right-click on the speaker icon (located in the lower right corner of the desktop in the system tray) and select “Detect sound problems.”
- A small window will appear. Click “Detect problems”. And we wait for the verification to complete.
