Public bug reported:
I have jackdbus running successfully (via qjackctl) in Kubuntu 16.10
with a Scarlett 18i8 USB interface.
If I turn the interface off, jackdbus will usually (not always -- I
think I may need to have played audio at least once?) jump to 100% CPU
usage (of a single core) and stay there indefinitely.
I can kill the jack processes, turn the interface back on, and restart
the processes, and things are fine again.
When the CPU usage happens, I see so further output in
.log/jack/jackdbus.log
Judging by jackdbus.log, I think I have "Controller" version 1.9.11:
Tue Dec 27 01:52:41 2016: Controller activated. Version 1.9.11 (unknown)
built on Sat Sep 17 05:04:38 2016
