I've applied the Windows UAA hotfix, I've tried multiple SigmaTel XP drivers, but can't get any to work (code 10).

All the other hardware, including the intel chipset/ graphics I was able to find XP drivers that worked. The audio is killing me, though and Gateway is unwilling to supply XP supported drivers for their Vista-marketed notebooks.

Any help would be GREATLY appreciated.

Thanks.
