You might check with just plain 'mixer'.  Sometimes soundcards have 
wierd mixer controls.  Also, have you tried pluggin your speakers
directly into the audio-out of the TV card?

Your X server or video card doesn't support DGA.  This isn't fatal,
although
you will notice a much higher CPU load while the TV tuner is on (coming
from
X, not fxtv).  Turning on DGA may be trivial for your card (Matrox users
for 
instance just define "WITH_MATROX_GXX_DRIVER" when building the XFree-4 
port), but that's a seperate issue.

Hmm, the bktr driver seems to understand your tuner, or at least it
thinks
it does.
