TC, I did know that. My own hands on research brought me to believe it was a driver problem. At least between CL's LiveWire 3 and DirectX 8.x. I would assume it was the same for the Turtle Beach cards. From what OriginalPhoenix said Turtle Beach fix this problem. CL didn't fix this for LiveWire 3 but did fix it for their new Audigy card.
Oh, sorry about my poor grammar. That "you people" thing, I was in a hurry.
