No Windows Sound when Gaming!? Help please :/

[sitheris]

I can listen to music in winamp or whatever just fine, but when I open up World of Warcraft or something all sounds in Windows MUTES. However, the sound in World of Warcraft works fine! If I let a song continue to play while I'm in WoW, and exit the game, the sound magically comes back. This isn't specific to winamp, it's ALL windows sounds. However, if I try to do Creative diagnostics while WoW is open, I can hear the speaker test, how crazy is that???

What can I do? I have all the latest drivers for all of my hardware, and I have the latest BIOS for my mobo. I've tried the SB in different PCI slots also.

Audigy 2 ZS
VNF4 Ultra
AMD A64 3200+ Winchester
1gb DDR400
Geforce 6600GT
Windows XP + SP2

Would it be possible that your onboard audio is configured and windows is outputting the sound through this?
Have you tried disabling it in BIOS?

It's already disabled. If it wasn't disabled, why would sound normally play fine when I don't have WoW open?

Can anyone help me?
