To test the Bluetooth A2DP playback, the Pulseaudio control module has to be loaded. In order to simplify the operation, turn on another terminal (terminal2) and load the control module in it.

# pulseaudio -D

In the meantime, the Bluetoothctl will load more control modules. Scan the Bluetooth in terminal 1.

[bluetooth]# scan on

Stop scanning after you’ve seen your Bluetooth device.

[bluetooth]# scan off

Connect to the Bluetooth device (Ex: Bluetooth headphone or speaker)

[bluetooth]# connect BT-addr

Check the terminal to see whether it has supported A2DP or not after connected the Bluetooth device.
