    Ubuntu audio via bluetooth dongle

1. Dependency

sudo apt-get install pulseaudio-module-bluetooth
and start the bluetooth daemon
sudo service bluetooth start
2. Configuration

Then from this edit etc/pulse/default.pa and comment out
(with an # at the beginning of the line) the following line:
[...]
#load-module module-bluetooth-discover
[...]

Then edit /usr/bin/start-pulseaudio-x11 and after the following line:
if [ x”$SESSION_MANAGER” != x ] ; then
    /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY ession_manager=$SESSION_MANAGER” > /dev/null
fi

add this line:
/usr/bin/pactl load-module module-bluetooth-discover

This way the Pulse audio’s Bluetooth modules will not be downloaded at boot time
but after x11 is started.
From this source now edit /etc/bluetooth/audio.conf
(create it if not present):
[General]
Enable=Source,Sink,Media,Socket

Make sure that in /etc/bluetooth/main.conf there are the following line:
[Policy]
AutoEnable=true

because otherwise your Bluetooth adapter will not power on after a reboot.
Then restart pulseaudio
sudo killall pulseaudio
pulseaudio --start

Then shutdown -r now.
3. Using bluetoothctl

Source. Plug the dongle and run bluetoothctl, then:
[bluetooth]# power on
[bluetooth]# agent on
[bluetooth]# default-agent

Then start scanning with
[bluetooth]# scan on

Now make sure that your headset is in pairing mode. It should be discovered shortly. For example,
[NEW] Device 00:1D:43:6D:03:26 Lasmex LBT10

shows a device that calls itself "Lasmex LBT10" and has MAC address 00:1D:43:6D:03:26. We will now use that MAC address to initiate the pairing:
bluetooth]# pair 00:1D:43:6D:03:26

After pairing, you also need to explicitly connect the device (every time?):
bluetooth]# connect 00:1D:43:6D:03:26

If everything works correctly, you now have a separate output device in pavucontrol.
NOTE: Once connected, remember to set High Fidelity Playback (A2DP Sink) in pavucontrol > Configuration.
To remove a device
bluetooth]# remove aa:bb:cc:dd:ee:ff
