Take a look through your dmesg log and see if what it says about btaudio 
and/or msp3400.  Also send the output of the 'lspci' command.  Those 
WinTV cards tend to be hit-or-miss as to whether you've got a version 
with btaudio support or not.

Keep in mind that the btaudio devices (in your case, /dev/dsp2 & /dev/
dsp3) are only for recording; you should still direct playback/output 
to /dev/dsp (or whatever your main soundcard out is).
