Good time of the day, Rob.

I have put Your config. files as You described.

Did modify QjackCtl.conf removing line w/

/home/band/headphone_monitor.xml

:o)

So  I started jackd manually:

$ /usr/bin/jackd -dalsa -dhw:0 -r44100 -p512 -n2
jackdmp 1.9.9
JACK server starting in realtime mode with priority 10

So, no luck for me. Ardour2 keeps saying of no jackd too:

From this output I see that Ardour2 does not recognizes my already
running jackd, so it starts its own w/o success.

I can use LMMS - it works even w/o jackd, but I want to setup things as
others (lucky people) do, and LMMS seems to me can not save .mid files.
