I have been having this issue for awhile, at least while in Win7. Where the cutscene in a game has no sound at all, but the rest of it is fine. I fixed this issue when I started using Creatives ALchmy program. I have installed a few new games since then and it does not seem to be helping. The current issue games that aren't working is Gears Of War and Rise Of The Argonauts. Any ideas, suggestions? I have onboard sound from the 780i SLI board if that helps.
