you can change a register and fix nearly all of the win2k/xp problems with the aureal cards. wpcredit can do it, and I think that 'pci latency' patch has it included. I couldnt get my old aureal to work with xp and my kt133, so I just bought an audigy, its nice but not a huge ammount better than my aureal. I didnt even try the register patch, it would have fixed it. oh well.
pick them up, $9 is cheap.
