Hello Sean, my friend recently borrowed me a N68C-S UCC, board and we installed Win 7 Ultimate 64-bit on a new hard drive and didnt have any problems, after that i started updating the drivers from ASRock > Products > Motherboard > N68C-S UCC > Download, all of the drivers I've installed have worked fine except the VIA sound drivers, the audio was working fine prior to trying to install the new drivers. I have tried many different ways to get them to work but the via device wont show up at all, only shows up as High Definition Audio Device, or has really bad audio quality when Windows Update installs the "right" drivers. Any help would be appreciated.
