In the past, qjackctl was shipped with Enable D-bus interface enabled. In the latest version, This option's meaning has changed :P to mean enable dbus interface to qjackctl rather than the old meaning of use jackdbus rather than jackd. The new version (April 6 2016) has a new option "Enable JACK D-Bus interface" which does not seem to be selected by default. As the ubuntu version of qjackctl already changes setting from default (48k is default to 44.1k?) setting this option to selected should be patched as well.
To be as clear as possible. The expected result of starting Jack with qjackctl is that pulseaudio will automatically load module-jack-sink and module-jack-source via the module-jackdbus-detect module. This no longer happens. To restore this the default setting for qjackctl needs to change to have "Enable JACK D-Bus interface" enabled.

I noticed this change, but thought that we need only the old option.
Now, should I enable only the new (Enable JACK D-Bus interface), or both?
