I tried btaudio a couple days ago and never got any output.
Here's what I'm guessing is going on. Anyone, PLEASE correct
me if this is wrong.
I think the btaudio module happily loads if there is a bttv
device present. However, it the card does not have an audio
chip like the msp3400 then there is nothing to be read from
the /dev/dsp* devices that the btaudio module creates.
Donno if this is correct. I only know that I don't have these
chips, I haven't gotten it to work and there's not much
documentation on how it's supposed to work.
