Nope, this is neither a Banshee nor Rhythmbox problem. Both Banshee and
Rhythmbox now use gstreamer1.0, while quodlibet is still using gstreamer0.10,
which is why you see the difference here.

Gstreamer-using applications require an audio "sink" to output sound. By
default, Ubuntu uses pulseaudio for sound output by default, which is provided
by gstreamer1.0-pulseaudio or gstreamer0.10-pulseaudio depending on the
gstreamer version you're using. If you remove pulseaudio, that sink fails, and
it attempts to fall back onto another sink, which in this case is jack (which
also doesn't work because you don't have jackd running).

The correct sink to use if you've disabled pulseaudio is probably alsa, which is
provided by the gstreamer1.0-alsa package. Please make sure you have that
installed.

Bug description:
  Lubuntu Raring (13.04).
  The Lubuntu standard installation comes without jack, and without pulse, just plain alsa. Gstreamer applications (rhythmbox, banshee) used to work fine after installing "ubuntu-restricted-extras", which pulls in the usual gstreamer plugins.
  On my system, gstreamer applications stopped working. They report:
  > Cannot connect to server socket err = No such file or directory
  > Cannot connect to server request channel
  > jack server is not running or cannot be started
  Since there is no jack on this system, never was, and is not intended to be there, I cannot understand this message. The applications do not produce sound.

  This looks like gstreamer tries to start up jackd, regardless whether
  it is installed or not.
