Title:
  Cannot switch to A2DP profile w/o restarting bluetooth.service
  [pulseaudio: Refused to switch profile to a2dp_sink: Not connected]

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When connecting to any Bluetooth device, PulseAudio fails to change
  its profile to A2DP (and leaves it in HSP/HFP).

  The following is appended to /var/log/syslog when trying to change
  profile in pavucontrol:

  Aug 14 14:59:02 k-laptop pulseaudio[18882]: Refused to switch profile
  to a2dp_sink: Not connected

  I'm currently using patched pulseaudio-modules-bt from here:
  https://github.com/EHfive/pulseaudio-modules-bt. But the problem
  persists with both packages.

  The working workaround I found is:

    sudo systemctl restart bluetooth.service
    bluetoothctl

      # list device MACs
      devices

      # use a MAC from the list above
      connect <MAC>

  After doing this, it is possible to switch to A2DP profile in
  pavucontrol. But such restart is required each time device is
  connected.

  I'm using
  Kubuntu 20.10 (development branch)
  pulseaudio: 1:13.99.1-1ubuntu8
  pulseaudio-modules-bluetooth: 1:13.99.1-1ubuntu8-9git+20200812~dfeee4f
    but also reproducible with 1:13.99.1-1ubuntu8
