Bug description:
  The `.log/jack/jackdbus.log` shows the following after trying to
  start/restart jack using "Ubuntu Studio Controls" (also tried using
  `jack_control start`):

      ERROR: Cannot lock down 82280346 byte memory area (Cannot allocate
  memory)

  This is a fresh install of Ubuntu Studio 19.04, installed via USB. The
  first thing I did after installing was check to see if jack was
  running, but unfortunately it's not working. The error would seem to
  indicate that I'm not in the `audio` group, however checking `groups`
  shows that I am in the audio group.
