A2DP Sink on Ubuntu Linux with bluez (streaming bluetooth stereo audio from smartphone to pc)

Howto Enable and Use A2DP Sink on Ubuntu Linux with Bluez

  1. Add Enable=Source to /etc/bluetooth/audio.conf right after [General].

  2. Find address in form XX:XX:XX:XX:XX:XX of phone with hcitool scan.

  3. Pair and trust smartphone with sudo bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX and sudo bluez-test-device trusted XX:XX:XX:XX:XX:XX yes.

  4. Create loopback in pulseaudio connection bluetooth a2dp source with alsa sink:

pactl load-module module-loopback \
source=bluez_source.XX_XX_XX_XX_XX_XX \

You can find your own values for source and sink with pacmd list-sources and pacmd list-sinks.

If this is for Streaming Audio from Ubuntu -> pulse -> bluetooth -> Phone?
Then it not work on Ubuntu 17.04:
pactl load-module module-loopback source=bluez_source.10_2F_6B_6E_14_06 sink=alsa_output.pci-0000_00_1f.3.analog-stereo
Failure: Module initialization failed

What does " pacmd list-sources | grep name: " produce?

Does your bluez source have .a2dp_source on the end of the name? I think there's a typo in the original post although things may have changed since then. My machine gives:

test@test:~$ pacmd list-sources | grep name:
        name: <alsa_output.pci-0000_00_05.0.analog-stereo.monitor>
        name: <alsa_input.pci-0000_00_05.0.analog-stereo>
        name: <bluez_source.94_7B_E7_XX_XX_XX.a2dp_source>

So I need

pactl load-module module-loopback source=bluez_source.94_7B_E7_XX_XX_XX.a2dp_source sink=alsa_output.pci-0000_00_05.0.analog-stereo

I'm not getting output but at least the loopback loads without error.

Edit: This worked for me:
