[LAU] Ubuntu 18.04 can't stop Jack from qjackctl

[Dale Powell]

If I disable D-Bus Interface and Jack D-Bus Interface in the Misc Preferences I _seem_ to be able to stop and start the server. But it's clearly still not working right! I can't actually change saved config without quitting and re-opening qjackctl. Even then it will something try and start the jack server automatically even though the Preference setting is set to not do so. Ontop of that no matter if I have dbus enabled I *always* get "/usr/bin/jackdbus auto" listed if i ps ax to see what is actually running.

Has somebody broken Jackd in Ubuntu?

Is it strange that I seem to have both jackd and jackd2 installed and to attempt to remove either wants to remove different selections of packages? Although this can't be the issue as this side of things hasn't changed in the last two weeks and this working as it should do has!

Hi all.

I've been using Ubuntu Studio since 14.04, always run with Jack as the main audio server and generally never had any issues. Upgraded to Ubuntu Studio 18.04 and everything was fine for some months but within the last week or so I can't get the Jack Server to Stop from within QJackCtl, the application just hangs, making it quite a pain to change between using my internal and external devices!

Any idea what may be causing this or steps to fault find the issue?

Currently I have set QJackCtl to not connect on startup, so I can killall qjackctl, kill -9 jackdbus(pid), restart qjackctl, select correct config and start the server running. So I can get on with my work but obviously it would be nice if things worked as they should again.

Regards, Dale.
