If the computer's operating system starts showing you an “Audio Output Device Not Installed” every time you move the mouse over a sound icon, this means that Windows may have problems determining the computer's audio device or it is possible that Windows Sound drivers are damaged. Usually, when you try to click on the Windows sound controller, it opens the “Play Troubleshooter” window to fix this problem, but it may not always solve the problem, and shows that “troubleshooting is impossible”, an error message on the screen PC, or perhaps sometimes it also shows that the problem is with the drivers.
The solution to the problem with the recognition of audio devices.
Causes of error
The error "Audio output device is not installed" can occur in any version of the Windows operating system, regardless of whether you are using Windows 10 or Windows 7 on your desktop or laptop, as well as on servers. Here is a list of things that might be possible and cause this problem in the computer system:
- Incorrect or outdated drivers (85% probability).
- Windows problems (14% probability).
- Malfunction of the audio connector of your PC, laptop or motherboard (1% probability).
And to find out what that means and which one is the main root cause for the “Audio output device not installed” sound issue on Windows 7 and others, you really need to troubleshoot, because without troubleshooting, no one can tell which of them is the main one. So let's see why problems occur and how to solve this problem.
What to do if the output audio device is not set
In most cases, problems are related to damaged PC drivers, and the best way to confirm this is to open Windows Device Manager, which lists all the drivers for the hardware.
What do we have to do? To do this, first, you need to open the Device Manager using a launch command called "devmgmt.msc", and in case you do not know how to open the "Run" window, press Windows + R at the same time, and then type "Devmgmt.msc" in the dialog box and press Enter. When the device manager opens before you, you need to check the sound drivers to know that everything is working fine or you may need to fix it.
Condition 1 - If the device manager shows you that the sound driver looks normal, and you still have this problem, then the PC or laptop has some basic drivers associated with it that cannot yet be identified. Or you can feel free to skip the solution to this condition and move on to the next one if there is some kind of abnormal sign on the PC sound drivers. In this case, you need to download the latest version of the PC sound drivers, which you can install after the download so that everything becomes normal again. If a driver update does not work for you, continue to the next solution to continue troubleshooting this error.
Condition 2 - if you find on your audio driver a yellow or disabled label that says, or perhaps all audio drivers are listed in the list of unknowns in the category of other devices, then it’s actually time that the PC audio drivers need to be updated. What to do if drivers are disabled? In case you find that Audio Drivers are disabled in Device Manager, you can quickly turn it back on by simply right-clicking on the Sound Driver and selecting the enable option, allowing you to turn the drivers back to the operating position.
What should I do if drivers have a yellow sign or are included in the category of other devices? A yellow or perhaps a red cross indicates that the drivers are damaged, and if the sound drivers are listed in the “Other devices” category, this means that the PC sound drivers on Windows 8 and others are not yet installed. In both cases, you will have to install the latest drivers, but if the PC shows a yellow or red sign on the old drivers, then you should first remove the old damaged drivers, because sometimes the latest drivers are installed. To remove the old drivers, you first need to right-click on the old sound drivers, and when the options appear, select “Remove” to remove this driver from the PC.
Troubleshooting the operating system
If installing or updating sound drivers to the latest did not solve the problem, in this case, the second most important and main thing that could be the cause of this problem is the own Windows operating system. In most cases, some kind of virus or, possibly, malicious software spoils Windows, and, basically, when malware or a virus gets onto a PC, it directly starts attacking programs and drivers to infect our system, and this is where the components run. which do some crazy things. So, the first thing to do is to scan your PC for viruses. What should I do if the removal of a virus or malware from my PC did not work? Basically, when malware or viruses begin to infect a PC, the main purpose with which they begin to spoil our Windows is the registry database, since it is the main controller of the Windows operating system.
It happens that anti-virus scanning sometimes did not show infected files on the PC, and yet you had this problem. This is only possible if the operating system was corrupted by any other spam software that you downloaded from the Internet while viewing an insecure website. To fix the registry problem, you just need to buy a best-in-class registry cleaner to repair and remove bad values from the registry database. All working registry cleaners are only available in the paid version, but before spending money, you can first fix the registry using the Windows command line, because in most cases you can solve this problem by entering one command and you don’t even have to pay anything for it.
Use SFC / SCANNOW to restore Windows. Sfc Scan is a great command-line command that can help you repair Windows just by typing one command at the Windows command line. Now you just need to type a command on the CMD and wait until the scan is complete, and it will restore most of the Windows files, including the corrupted registry database:
- Open CMD as administrator.
- Then type “sfc / scannow” and press Enter. Make sure you do not close this CMD window until the check is 100% complete.
- Restart the PC and check it, if the sound returns, then it is good, if not, now you need to buy a registry cleaner for the operating system.
If your PC does not have a tuner or registry cleaner, install the best-in-class cleaner on your PC to achieve perfect system performance and uptime. After downloading the registry cleaning program, simply click the scan button, which will automatically start a full system scan, and then it will show you every little problem found on your PC. After that, just click the "Fix the problem" button to restore everything that is displayed in front of you.
In case you still have this problem on your PC, it is possible that some important Windows files were damaged from the inside, and there was some problem that still prevents these files from fixing and working correctly. The only way to solve this problem is to reinstall Windows. Sometimes it happens that recovery is impossible. Thus, backing up and installing new Windows on a PC is the best option you can still try, and perhaps be sure to install the latest drivers, according to the version of the operating system after the Windows installation is complete.
Even after reinstalling Windows, if you still have this problem with the PC, then this is a 100% hardware error, but there are some things you can still try - restore the PC sound by troubleshooting hardware problems. Troubleshoot the output device - it is sometimes possible that the audio output device you connected is already defective, and Windows is writing an error due to this faulty output device. In fact, it is always better to use headphones or earplugs in the audio jack of a PC or laptop to check for their internal or external problem.
Use a different audio jack (for desktop users only). If you have this problem, you can also try using the audio jack on the front panel of the PC, in addition to the rear panel, and if you already use the jack on the front panel, you can also try using the jack on the back panel, because everything is possible It works fine, but the problem is with a broken audio jack. Use the USB Sound Adapter is an external audio output device that you can use in the USB port of a PC or laptop, because repairing an Audio Jack or Audio Chip on a PC motherboard is really expensive, but for less than $ 10 you can buy a USB sound card for your PC, which can work on both laptops and desktop PCs.
Setting up the playback device
The sound function in Windows only works if there is an installed audio device in the system, and its absence will interfere with normal operation. Sometimes users encounter the “Audio output device not installed” error when they scroll the mouse over the sound icon that is in the lower right corner of the PC screen. Because of this error, the audio function of the PC stops working. This error can occur in any version of the Windows operating system, be it Windows 7, 8 or 10, depending on what you are using.
The error occurs when Windows is damaged and is faced with an identification problem with the computer device, or if the Windows Sound drivers are outdated or damaged. This can also occur if the computer’s audio jack has a malfunction. However, it is difficult to determine the exact cause that causes problems with the sound in the system. The sound icon displays a red X on the screen during an error, which indicates that the computer cannot make sound at this time. Many Windows users often complain about this problem.
