what is your current "configuration" and for what purpose do you use
the install? Usually I launch jackd hassle-free by a script or
by an application like Ardour, but sometimes I start it using qjackctl,
always without any hiccups, too.

I'm not using jackdbus and pulseaudio is even not installed
on any of my systems.

Perhaps you try to start jack, while pulseaudio already grabbed the
device or if you should run a "keep it simple" set-up as I do, you maybe
launched a browser using the audio device, before you started jack.

In short, the issue unlikely is related to the qjackctl configuration.
The issue much likely is caused by the configuration of your system,
conflicting with the desired usage.

To solve the issue instead of guessing how to solve it, we need more
information, at least the complete output of jack.

However, using pulseaudio and jack at the same time at best is only
useful in exceptional circumstances, so assuming you should use both
sound servers, consider to stop pulseaudio or to use a bridge.

If you should use a set-up without running pluseaudio and you e.g.
started a browser using the audio device, before you launched qjackctl
to start jack, don't do it this way.
