I'm confident that this is a Vista issue. I guess, I'm gonna have to sacrifice DX10 and switch back to XP.
odd that onboard audio is doing the same thing you were having issues with the X-Fi, considering those are two different styles of audio playback and drivers are different.
By chance, the issue you are currently having with your onboard audio, is it exactly the same as with the X-Fi card, or are there differences?
If it is exactly the same, I'd reason to say that the problem might possibly be with your speakers - in this case, I'd recommend trying another set if you have them, or, try hooking your speaker setup to some other form of device, like a TV, DVD player, DVR, stereo, etc. If the problem is still apparent, the speakers themselves might be defective - rare, but not entirelly impossible either.
