I've encountered a problem lately where I couldn't get any audio from my on-board sound card. It just suddenly stopped after I booted it up the other day. I haven't installed any software or drivers that could conflict with the system before that.
I have a Gigabyte GA-H81M-DS2 (Rev 3.0) motherboard running Windows 7 (64Bit) with updated and proper drivers installed.
Solutions I've already tried:
*Reinstalling the drivers. (Uninstall -> Action -> Scan for hardware changes)
*Restarting Windows Audio from Services.
*Running the Windows built-in troubleshooter.
*Speakers set as default device and not muted.
However, I tried my external USB sound card which is a, Creative SB1140, plugged it to my PC and plugged my speakers to the USB sound card. The sound played perfectly fine. I really have no idea what caused this. I really need your help guys.
