Overall Im fine with the changes, but how would we could dynamically
control the auto loading? Im not sure this will always be static which
apparently is what it implicates by being in
module-bluetooth-discover, lets say in some conditions the audio
should not be send back to loopback or loopback is not the default
sink/source.
