i just tried using it as my main output. it works fine with WMP but itunes, the songs are all studdered. and the defualt windows sounds are all fucked up too.
itunes might be 44.1khz but windows sounds are 32khz... so if you record at 96khz neither will play right...or if it does happen to switch automatically it won't go back to the 96khz right...
OR
Whatever is producing the sound uses some sort of processing...like Direct3D for games...
