Hmmm, there is a process:

bill      2051  0.0  0.0  24432   592 ?        S    09:46   0:00 
/usr/bin/dbus-launch --exit-with-session /usr/bin/im-launch 
/usr/bin/cadence-session-start --system-start-by-x11-startup 
cinnamon-session-cinnamon

but not an explicit cadence process. It would seem that firing up 
cadence once has set something and that is enough.
I'm able to run Qjackctl with any problems, and get sounds from totem etc.

Once again, many thanks for guidance and advice!

Bill
