that pasuspender wasn't the solution probably. My .jackdrc is different then the settings in qjackctl. Maybe there might be a problem then. The .jackdrc file is updated when changing settings in qjackctl, but not with the same -p values.

-rw-r--r--  1 user user        56 Jun 13 20:35  .jackdrc

cat .jackdrc
/usr/bin/jackd -v -dalsa -dhw:CODEC,0 -r44100 -p128 -n2

I should clarify things a bit.

qjackctl as it comes, normally does not run jackd but rather jackdbus, it is possible to make it run jackd instead with settings.

qjackctl does not write (so far as I know) .jackdrc directly. Rather, when jackd is started, it writes that file as a copy of the command line used to start jackd.

jackdbus does not use .jackrc at all.

So if you start jackd with no parameters (as you did with pasuspend -- jackd) it reads in that file instead. If qjackctl then tries to start jackd with the settings it has, it either finds jack is already running or tries to start jackd and fails. In either case the settings in qjackctl would have no effect.

Anyway more stuff to study...
