For everyone with problems getting btaudio to stick to a particular dsp
device, add the following options to your modules.conf:
options btaudio dsp1=x dsp2=y mixer=z
where x,y & z are the numbers of the device. So,
options btaudio dsp1=2 dsp2=3 mixer=2
would give btaudio /dev/dsp1, /dev/dsp2 & /dev/mixer2
