Hi Everyone

I recently moved all the parts of my PC into another case, and in the process I have lost all sound.

I have had absolutely zero issues with anything else, the computer is functioning completely fine and the only issue is that I cannot hear anything through speakers or even USB headphones.

I have exhausted all possibilities and have concluded that the onboard audio card must be damaged as a result of the PC case change.

My question is essentially is it possible to use my Nvidia GTX graphics cards as an alternative for the onboard audio, rather than purchasing a PCI-E Soundcard.

I have a Micro ATX and have TWO graphics cards, and cannot fit a PCI-E Soundcard without taking one of the graphics cards out


Thanks!

You can get audio out of a GTX6xx or better only out the HDMI connection. Thus, if you want to use desktop speakers you require a monitor with HDMI input and audio output to attach to your speakers (or use crappy monitor speakers).

I believe it's not passthrough from your audio solution but not 100% certain so you'd just have to try it.

You'll want to disable your onboard audio in the BIOS. Not critical but no point in being there. Also you need to enable NVIDIA HDMI in your "playback devices" but if onboard audio is disabled it should be on my default.

(I am surprised you lost audio, but if it's enabled in the BIOS it should work. You may wish to boot to a Linux disc such as Ubuntu for an easy test to see if your onboard audio still...

Onboard audio checklist:
1. enabled in the motherboard BIOS
2. enabled in "Playback Devices"
3. Windows audio is high enough (i.e. 50%)
4. Speaker/headphones connected properly and functional
5. Drivers/software properly installed

Is it possible the motherboard isnt damaged and windows might need to be reinstalled? In device manager the realtek HD audio device appears to be functioning as normal on internal audio bus
