From the google search I found this, it won't cure the problem directly
but may give a starting point. Mind the 'tvaudio' line..

I know this chip, I used it in a mp3 car project once. It has volume
control for Left and Right and Fader control for 4 outputs and bass,
treble, source input select etc.
So if your TV card has this chip, you have a mixer also.. :-)
And as far as I know every BT848/878 has a mixer too, so you could have
a total of three mixers (that's including the mixer of your default
Hope you don't get too 'mixed up' by this... :-)
