Let me guess an A7N8X-E Deluxe, or some variant? I have the same 
motherboard, with the same onboard nvidia chip. I know there are some 
people out there who have the sound on this board working no problems, 
but I have never been able to get it to work. It infuriates me, every 
time I upgrade Fedora versions I resolve to finally figure this out, 
waste hours tinkering then put my PCI sound back in.

I've never had windows on this motherboard so I don't know if it works 
there, Fedora's sound wizard finds the chip just fine. Modules get 
loaded, and if I play an mp3 I see a little progress bar moving just 
like its playing, but I can't hear anything. I've checked volume levels 
with every mixer I can find, and I've plugged the speakers into every 
port including the mic port just for the hell of it.

I've read on countless forums. I remember one guy saying he disabled his 
onboard nvidia network port and suddenly the sound worked. I tried that 
and it didn't help.

So, sorry to say I don't have much advise for you, if you figure it out 
let me know. :-/
