  I am still wondering about the difference between
qjackctl's "JACK D-Bus
 interface" and its "D-Bus interface" by the way. Enabled both. 
One is the D-BUS interface that jackdbus provides and, when enabled,
causes qjackctl to start/ connect to jackdbus instead of running jackd,
the other is the D-BUS interface which the qjackctl application
provides, which you probably won't need.
