luckly I'm not that much of an audiophile as some people and stoped useing creative sound cards after my 16bit soundblaster (which I kept useing for a good while) I only stoped useing it due to lack of drivers and the improved performance of onboard realtek sound chips which give me good enough audio quality.
EDIT: I'm guessing that this was the 3rd party IP
X-Fi:
Got Dolby Digital Live enabled on any X-Fi card. To clarify, I still didn't manage to enable DDL on Audigy cards.
A friend of mine bought a X-Fi, so I could test it, it really works.
The only current X-Fi based card that supports DDL is the Auzentech Prelude.
However from what I read I don't think he released that in his drivers just said that he'd done it.
