Well, its removal of DirectSound3d.. its NOT removal of HW accelerated 3d sound afaik..
There are other APIs, like OpenAL, and FMOD (EX) that WOW and BIOSHOCK (EDIT: and Crysis apparantly) uses.
Dunno much about FMOD, but I know the programmers in my class use it alot.
With no DS3d in Vista, games will start using other APIs.
