Okay, perhaps IDUC ;) But I think that my understanding is actually
probably correct, just that there's something wrong with the bluetooth
subsystem. I've spent far too much time myself trying to get a
bluetooth headset working under linux, and it was incredibly
frustrating. The documentation is (was? it's been a while) horrible,
inconsistent, ridiculously sparse and outdated.

So I'm guessing that the system works the way we understand it, just
that something's wrong with the bluetooth part. Perhaps the other
applications are failing to connect to the bluetooth device and are
therefore defaulting to the SB?

I've never used Pulse.
