He was reporting on the default, i.e. audio backend via portaudio.
It is not surprising that he can still see this - it vanished for you
before I fixed the play-button-redraw call, so although that will have
caused the strange gtk behaviour I saw, there will be another threading
bug there somewhere.
BTW I have occasionally had Denemo blurt out a heap of music when
starting play again, as if it hadn't sorted out the start time or
cleared the buffers or something. But it seems to be quite rare, as
threading bugs often are I fear.
