Title:
  pulseaudio can't switch to internal audio when a tunnel sink is
  present

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  I recently added the module-tunnel-sink to my pulseaudio config to
  have an  option to tunnel audio to remote server.  The tunnel works
  fine, it shows up in 'pavucontrol', and audio sounds fine.  However,
  when the tunnel is connected, if I go to the 'playback' tab in
  pavucontrol and switch audio that is currently playing to 'internal
  analog stereo' on my T500 laptop, then audio stops playing on the
  remote server, but it never starts on the local laptop speakers.    As
  a further symptom, when I press pause on the audio (it's mog.com
  playing in google chrome), the audio stops within a second, but when I
  undo pause, it takes maybe 15 seconds to startup.  It doesn't do that
  when the tunnel is not present.

  I was hoping to be able to use the tunnel so I could 'seamlessly'
  switch between remote and local audio, but at the moment, it seems
  like setting PULSE_SERVER when starting google chrome and connecting
  directly to the remote server seems to be more stable.  But the
  downside is it requires restarting chrome each time I want to switch.

  It'd be great if I could get the tunnel to function seemlessly.  I've
  turned on DEBUG level logging on the pulseaudio client and server.  I
  don't see much helpful there except things about buffer underruns
  periodically and 'Wakeup for ALSA' messages.  But the underrun related
  pauses are only a few hundred milliseconds.
