Great info,

thanks a lot.  I'll try that.  By the way, what is your entire alias line for 
btaudio from modules.conf?

It's a bit confusing, though, on second thought.  Why does mythmusic work 
then?  If it's using /dev/dsp0, and that is laready taken by btaudio (I 
presume both for playback and recording) then playing through it won't 
produce anything?  Hence, I shouldn't be hearing mythmusic output either.

One more interesting detail is the fact that I loaded btaudio only once.  When 
I get the error I described before, I haven't even loaded btaudio.  Bizzare.

Thanks,
IvanK.
