Today I found out that the sound stopped working on both Win 7 and Win 8.1 systems installed on my home PC, whereas it still works perfectly fine on Debian running on the same machine. I haven't touched anything related, so I am not sure what could be the reason.

How can I debug what is wrong? I don't really know where to start. All the drivers in hardware manager seem fine. I am just using the sound card in my chipset (old Asus board based on Intel chipset, from the Core 2 Quad era) with standard Creative speakers connected using a mini jack.

EDIT: Windows doesn't seem to recognize that my speakers are plugged in, maybe the graphics chip stopped reporting this correctly. Is there a way to force it to play regardless?

Are you sure the problem is in the computer? Maybe try turning the volume knob? Turn off and back on? Delete the audio device and reinstall? BIOS options favor built-in audiocard? Try remotely listening to music via Teamviewer? A discrete audio card could help, perhaps? –  user1306322 Feb 8 at 21:39
    
@user1306322, the hardware works fine in Debian, so I have no reason to believe that anything apart from software configuration is wrong for some reason. –  Grzenio Feb 8 at 21:44
    
Well, then have you just tried all of the listed things? –  user1306322 Feb 8 at 21:53
    
Try to remove the sound driver and install the driver again. Are you able to see your sound card in computer management? –  user2301394 Feb 9 at 8:28
    
@user2301394, how do I do it? It is the standard driver that comes with Windows. –  Grzenio Feb 10 at 8:51
