I had a problem a bit like this. The way I resolved it was to do two things:

1) Turn down the volume to about half on the cable box
2) Unselect "Input Is Surround Sound" in AMix (I think, but I guess it 
shouldn't matter as long as the mixer you use shows the sound card 
switches) which is in the "switches" tab. This was the thing that made 
the most difference, before that the sound was terrible.

Note that sound from XawTV etc., is direct from the line in, and so will 
be uneffected.

I hope that helps!
