I just got an SB Audigy card, and am running Win XP PRO (CE). THe card didnt auto install like my SBLIVE! gamer 5.1. It kept asking me for drivers on boot. I stuck the cd in and ran a custom installaion (only installing what I needed; playcenter, audio hq, etc...)., then rebooted it and it worked perfect. Much better quality sound that the Live card. I ran one of the demos to test the ac3 pass thru (that never worked for me under 2k, no matter what I did. not even playing dvd's could i get sound out of my center channel) and it worked awesome! Played a dvd and total 5.1 sound! Finally, I am totally satisfied with my system. Except for wanting a P3-s 1.5.
my 2 cents...
