I'm guessing this would have to be related somehow to
the mediacapture-output API, since that's what is actually choosing which
physical device the audio gets sent to. Am I right?

I understand that this might not be available on all media outputs, but
it's a good signal to have.  This is something I would be keen on
requesting for as well.
