Yes, jackdbus is launched.

OK, thanks.  I modified it, restarted the system and now all the proper
parameters are there.  And the jack sink pulse.

The latest modifications in qjackctl were not saved.  It showed 128,
jackd was launched with 256.  I do not know where qjackctl fished out
the 128 value to show in the GUI.

Just about everything can be restarted.  It might be a matter of
defining 'standard way'.

A few moments ago I stopped jackd, without taking care of stopping
Mixbus 3.1.  There were some edits not saved (not much as I save very
often) and Mixbus would not save them when exiting, because jackd was
gone.  This is not likely to happen, that jackd goes away, although in
such cases data should be saved nevertheless.
