Hi Isaac,

I'm having problems setting up btaudio as well.  I definitely have a
pci audio capture device and btaudio finds it, but I get no data when
I read the digital dsp, and I get a square wave when I read from the
analog one (I've tried all three inputs on the btaudio mixer).  Does
your bttv find either the MSP34xx TDA9875 or TDA7432?  Could you
provide the dmesg output of your bttv and btaudio drivers or take
a look at the output of mine to see if anything looks amiss?
