Public bug reported:
While I was using Saucy I could launch jackd and pulseaudio would
configure itself nicely as a jackd client. Since upgrading to Trusty I
can no longer launch jackd because the audio interface concerned is
"already in use" (by pulseuaudio). I am pasting the output of qjackctl,
covering a few attempts to connect, below.
