edit:

tried an old cleative labs soundblaster live card in and set that up ok,

now ive got sound on games, windows dvd player but not on my ATI tv display, ive tried the audio outout from my 9800pro in all the creative ports but still no sound, at least my sons stopped moaning but would still like to get the tv sound going.

Fixed it now, not sure why but direct capture on the tv setting seemed to mess it up disabling it and configuring the audio options has soerted it.
