JACK is living-dead

[bad sector]

os-12.1(64), latest updates:

I've read that one of the best ways to start JACK is via the audio
connection kit dialog start button. What I'm trying to get to produce
sound is the hydrogen drum machine which also tries to start JACK.
Clicking the connection kit start button ends up with the error list
shown below. However, if instead of trying the connection kit I launch
ZynAddSubFX (started using padsp zynaddsubfx) then hydrogen works no
problem. The connection kit still fails, and if I try to shutdown the
synth while hydrogen is up all the synth dialogs just lock up and it
will not quit (until I kill hydrogen).

Seems like maybe wrong JACK startup procedures (except for the synth)?

Does anyone understand what's going on and how to fix it?

TIA
