Hello experts here, does anyone here know where the 'test button' on output devices and input devices goes?

I once experienced an error during a test on the sound output device.

 

At that time I had tried several things, but failed:

  • Using SFC (System File Checker)
  • Uninstall and reinstall the audio driver

Things I hadn't done when the error occurred:

  • Checking the System event

The last thing that finally solved my problem at that time:

  • Using System restore

Also help with this problem if there are experts who know about this.
