So wtf? Turns out my onboard Realtek ACL888 chip sounds at least twice as good as my A2ZS did in Vista. I decided to ebay the ZS to get an X-fi eventually but I'm not even sure I'm gonna bother now. This Realtek hd audio sounds way better in games and although I haven't tested it much in music and movies it is at least even in those. Even stranger, I actually get more fps in UT3 with the onboard Realtek. I think this just goes to show how bad Creative's Vista drivers really are. The only advantage the A2ZS had was being able to use OpenAL in that game which made a few of the effects sound a little more correctly positioned but besides that this onboard audio blows my mind lol. Weird thing to is for some reason my Sennheiser HD555s are a lot louder, more powerful sounding with the Realtek at least when the cp is set to headphone mode. It's like they weren't getting enough juice from the A2. Even funnier my A2ZS just sold for $80 lol.
