I guess you're hearing glitches in Ardour in this case? so ask Ardour
developers for that specific "known" issue... ((-:
jack2 does not interrupt the audio stream, but AFAICS some clients
(like Ardour) can not handle notifications (like graph reorder...)
that are delivered in a second non RT thread on jack2, without
stopping their RT audio process.
