For those still using Audigy soundcards, Creative has released some new drivers for Vista, as well as XP. These drivers add Dolby Digital Live support. Go here - Creative Worldwide Support, select your card, get drivers.
Doesn't seem to be any new Vista drivers for the Audigy SE but there are Windows 7 drivers which is nice if I don't decide to get a newer sound card by the time W7 comes out.
