Sorry I disagree, qjcakctl has given me nothing but trouble and still
does.
It goes much better without it.
All it arguably does is to formulate a jack string....which the user
should do on command line anyway, and then output mystery log errors
which are substandard to reading the logs yourself.
I have never found any constructive use for it other than "feelgood".
Mixbus worked great once I removed qjackctl on my previous system.
qjackctl was single most annoying interference problem.

As I reported already in another post it is recognised.

As already reported, mixbus starts jack and jack runs IFF I dont start
jack with qjackctl. Once qjackctl started jack, mixbus wont work. Mixbus
starts jack with a string they disclose in the terminal output and it
works.
According to patchage as I reported in a previous post, mixxbus is
connected to jack, but I get no signals from jack for the 1818vsl inputs
in mixbus.

I know I am just trying my documented default settings that worked
perfectly before.
