I installed one of the few games I actually own, Battlefield 2, the sound is choppy and my 5.1 is inactive(in game and out) which I may have to find some AC97 audio drivers for vista if possible. Also when I go to multiplayer a huge polygon looking thing starts flashing like a rave but I can randomly join games.
Just a matter of time until programs like alcohol are imported over.
EDIT : I tried the vista beta sound drivers from realtek but still got an error and no surround, the beta vista drivers from ATI for my graphics card worked perfect though
