I have purchased a M-Audio AUdiophile USB sound card to go along with my Media Center PC. I have trouble getting the AUdiophile USB to work on the Media Center PC, but no problem whatsoever on my XP latptop. (I downloaded the most updated driver from M-AUdio website already). I wonder if there is anyone out there that have similar experience, and how they resolve the issue. Does the MCE constructed very differently than the XP pro?
