Solution 5: Do Some Checkings 

If the solutions mentioned above fail to work, you need to do some hardware and sound settings checks. These are not such complicated actions to take. 

Usually, when an audio device does not work, we take these basic actions initially. For our slightest eye rolling, these can be a mistake. 

Check The Sound Settings Of Your PC 

Check if your volume is audible. Ensure the sound on your pc is not muted. Increase the volume to see if the connected devices work properly or not. 

Check if the connected audio device is selected as the output device on the sound settings. Select both input and output devices correctly. 

Check The Hardware 

Check if any of the cables are damaged. A twisted, worn-out, or damaged wire can cause audio and sound settings trouble. 

Also, check if the audio devices are connected to your PC through the correct cable and port. Do not mix up the ports with the cables. 

Solution 6: Going Back 

Rolling back the driver or rolling back the windows means returning to the previous software version. 

You did not update your software to return to the previous version. So, I kept the rollback option as the final solution. If any solutions do not work, we have nothing to do except return. 

How To Roll Back The Driver? 

  • Hit the Windows key + R together to open a Run
  • Type devmgmt.msc and hit the Enter 
  • Double-click on the Sound, video, and game controllers option

  • Now hit Ok 

How To Roll Back The Windows?
