Please temporarily stop pulseaudio, since I don't have pulseaudio installed and I never used it, I'm not sure how to do this, but I guess running
pulseaudio --kill does the job nowadays, after that run qjackctl and in "Settings... > Misc" uncheck "Enable D-Bus interface", then start and stop and close qjackctl, ignore error messages when starting, I only want to ensure, that D-Bus is disabled by the settings, what ever version of qjackctl you are using. In a terminal run jackd -dalsa -dhw:1 -r48000 -p1024 -n3 and assumed it shouldn't work run jackd -dalsa -dhw:0 -r48000 -p1024 -n3 Normally it's better to use "-n2" and go lower than "-p1024", but for testing purpose "-p1024 -n3" are good values. After starting jackd in a terminal, you can start qjackctl.
