Hi guys, I was hoping you might be able to help me with my problem. Couple days ago I turned on my computer and my sound wasn't working. I've tried downloading the drivers from DFI site and drivers from nvidia and I checked my BIOS to make sure my sound was enabled. I have a DFI LANPARTY UT NF4 ULTRA-D motherboard. And under dxdiag on the sound tab everything is blank.
