Autoconnecting seamlessly to Bluetooth headset (Sennheiser Momentum M2 AEBT) in Ubuntu 16.04

Solution 1:

The following solution worked for me:

  1. Check to see if the module-bluetooth-discover is loaded: pactl list short | grep blue If it's not in the list then:
  2. Load the module: pactl load-module module-bluetooth-discover

You might want to reload it even if it is in the list. Then, try to connect again to the audio sink for High Fidelity sound.
