Thanks for the specs.  Unfortunately they did not work for me.  My xmms 
locked up on every attempt and I did not aquire sound in any of the TV 
application I have installed.  I sure had a ton of modules loaded up 
though :)

I think I may just buy a sound card.  I've had this brooktree tv card 
working with linux before but it was with an external sound card that is 
currently required in another pc.  I have never really liked onboard 
sound but my board came with it so I was trying it.  Oh well, thanks all 
the same.
