The little experience I have with bluetooth headsets is on Openmoko, and that 
has unusual bluetooth audio routing. I have 'profile "auto"' after the 
'device' line in asound.conf but I don't know if it's necessary. I haven't 
tried it with linphone yet.

The errors look like driver errors. I don't know what linphone might be doing 
to provoke them though.
