Title:
  Bluetooth audio devices/profiles are missing after logging in from GDM

Status in gdm:
  Unknown
Status in PulseAudio:
  Unknown
Status in gdm3 package in Ubuntu:
  Fix Released
Status in gdm3 package in Debian:
  New

Bug description:
  This is actually a PulseAudio bug, but the workaround is to disable
  Bluetooth audio in GDM.

  Further discussion (and the source of my understanding about this
  issue) upstream are here:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805414

  To summarise:

  GDM opens the A2DP profile for a11y purposes to allow screenreaders to
  output over BT audio devices. However Pulse doesn't release those
  devices when no audio is being played and the upshot is that once in
  the users session A2DP is not available for any Bluetooth audio
  devices, this means that you can only use the low quality profile
  HSP/HFP.

  There is a proposed workaround, but this means that a11y tools which
  need to output audio won't be able to use Bluetooth devices within
  GDM.

  I think that for 17.10 shipping this work-around is acceptable, and we
  should revisit in the 18.04 cycle to try and get a proper fix in PA.
  The suggested PA bug is:

  https://bugs.freedesktop.org/show_bug.cgi?id=57167

  but that hasn't seen movement since 2012.

  = The work around =

  From the Debian wiki:  https://wiki.debian.org/BluetoothUser/a2dp

  Disable the Bluetooth sink in the GDM PA daemon.

  Add this to /var/lib/gdm3/.config/pulse/default.pa

  #!/usr/bin/pulseaudio -nF
  #

  # load system wide configuration
  .include /etc/pulse/default.pa

  ### unload driver modules for Bluetooth hardware
  .ifexists module-bluetooth-policy.so
    unload-module module-bluetooth-policy
  .endif

  .ifexists module-bluetooth-discover.so
    unload-module module-bluetooth-discover
  .endif


  I have tested this, and I can confirm that it allows access to A2DP
  again in the user session.
