That's not a solution, that's the goal Creative seems to have with their lack of support on Audigy cards.
Besides that, the audio quality of the Audigy cards themself are just fine, the X-Fi just has more hardware acceleration and effects.
I have an Audigy 4 under Windows XP, and had three BSOD's so far. The last one on opening a medkit, the others at random. I debugged the minidumps Windows made, and it turned out the exact file it started crashing on was hap17v2k.sys.
I was running the drivers Windows gave me through...
