I am going to guess that the audio function of the BT-878 is for recording
of e.g. FM radio broadcasts? If so, then you'll need to have the bktr driver
in your kernel with a "radio" sub-device configured, and use a radio control
program to tune the receiver...
Having said that ... this is cool -- I have a BT-878, and I would love to
be able to archive _Fresh Air_ broadcasts more easily :-)
