I think mplayer only initialize (unmute) audio-out of tv card. You can 
watch tv with sound when the audio-out of tv card and audio-in (line-in, 
aux, cd-in) of sound card are connected. Mplayer is not able to route 
audio (am I wrong?). When you choose adevice=/dev/dsp2 you choose it as 
audio-out.
To use btaudio module you should conneect some amplifier directly to 
your Osprey - then you should have to configure it such as second sound 
card (I never tried it then I do not know how) - check your sound mixer 
for second panel?
