otoh, releasing the audio backend, allows other software to steal the
audio card.
i think this is a feature not a bug.

instead, i think that re-connects should not fail instead.

i think that Pd should definitely have a method to release the audio card.
currently it is really complicated to start Pd in ALSA, then starting
jack outside of Pd and then connect Pd to this instance of jack.

probably a "dummy" audio-backend would help here: this would allow to
separate the DSP on/off functionality from the audio-backends.
