It wasn't a problem with jackdbus auto.
In this thread I accidentally found a hint that, without me noticing, the server name changed itself from "(default)" to "voreingestellt" (, which is german for "default".)
I'm running Xubuntu 16.04.3 LTS xenial Kernel: 4.4.0 Lowlatency
It all starts with the error
Ignoring JACK server start request because server is already started.
when I want to start the PulseAudio Bridge in Cadence.
I had this before and killing jackdbus auto allowed me to start a fresh instance and got it working (as fragile and unstable as jack works then). However, I am absolutely unable to kill jackdbus auto, no matter what I do.
- Taskmanager > right-click > kill
- kill pid
- kill -9 pid
- killall jackdbus
- killall -9 jackdbus
2 and 4 do absolutely nothing.
1, 3 and 5 cause the process to be killed but being auto started again right away with a new pid.
Since it's called jackdbus auto I can assume that it starts automatically but how in the world am I supposed to solve the error/message when trying to start PulseAudio Bridge in Cadence?
