The difference between the pro and non-pro versions of the
miro/pinnacle cards is that the "pro" ones have a msp3400 chip
and the others don't.

I suspect what happens is that the bttv driver doesn't find the
msp34xx for some reason, thus handles the card as non-pro version.
Which will work just fine, the only difference is that the sound
routed to the line-out isn't the stereo signal from the msp34xx but
the mono signal from the tuner chip.  It isn't that obvious that the
card isn't handled correctly because you will get sound, it just isn't
a stereo signal ...

Without msp34xx being programmed correctly the chances that btaudio
works are close to zero.  With msp34xx it might work, I don't know for
sure.

Are there any messages from the msp3400 module in the syslog?  What
happens if you try to load it manually?
