Install dependencies:

sudo apt-get update
sudo apt-get install wajig
wajig install dh-autoreconf libasound2-dev libortp-dev pi-bluetooth
wajig install libusb-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev libsbc1 libsbc-dev

Compile Bluez 5.52:

git clone git://git.kernel.org/pub/scm/bluetooth/bluez.git
cd bluez
git checkout 5.52
./bootstrap
./configure --enable-library --enable-experimental --enable-tools
make
sudo make install

sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so
sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so.3
sudo ln -s /usr/local/lib/libbluetooth.so.3.19.0 /usr/lib/arm-linux-gnueabihf/libbluetooth.so.3.19.0

Compile Bluez-Alsa

cd ..
git clone https://github.com/Arkq/bluez-alsa.git
cd bluez-alsa
autoreconf --install
mkdir build && cd build
../configure --disable-hcitop --with-alsaplugindir=/usr/lib/arm-linux-gnueabihf/alsa-lib
make
sudo make install

Configure Bluetooth subsystem: Create file /etc/bluetooth/audio.conf

sudo nano /etc/bluetooth/audio.conf

add

[General]
Class = 0x20041C
Enable = Source,Sink,Media,Socket

Update file /etc/bluetooth/main.conf

sudo nano /etc/bluetooth/main.conf

add

[General]
Class = 0x20041C

Automate BluezAlsa: Set BlueAlsa as a service Create file /lib/systemd/system/bluealsa.service

sudo nano /lib/systemd/system/bluealsa.service

add

[Unit]
Description=BluezAlsa proxy
Requires=bluetooth.service
After=bluetooth.service
[Service]
Type=simple
User=root
Group=audio
ExecStart=/usr/bin/bluealsa --profile=a2dp-sink
[Install]
WantedBy=multi-user.target

Enable BluezAlsa starts from boot:

sudo systemctl daemon-reload
sudo systemctl enable bluealsa.service

Set bluealsa-aplay as a service: Create file /lib/systemd/system/[email protected] hw1:0 is the hifiberry audio device I want to use. Use aplay -l to check. There may be better way to link it.

sudo nano /lib/systemd/system/[email protected]

add

[Unit]
Description=BlueAlsa-Aplay %I -dhw:1,0
Requires=bluetooth.service bluealsa.service
[Service]
Type=simple
User=volumio
Group=audio
ExecStart=/usr/bin/bluealsa-aplay %I -dhw:1,0
[Install]
WantedBy=multi-user.target

Add UDEV rules Create file /etc/udev/rules.d/99-input.rules

sudo nano /etc/udev/rules.d/99-input.rules

add

KERNEL=="input[0-9]*", RUN+="/home/volumio/a2dp-autoconnect"

Tell Bluetooth how to create a bluetooth->Alsa connection: Create file /home/volumio/a2dp-autoconnect

nano /home/volumio/a2dp-autoconnect

add

#!/bin/bash
# at each BT connection/disconnection start/stop the service bluealsa-aplay
function log {
        sudo echo "[$(date)]: $*" >> /var/log/a2dp-autoconnect
}
BTMAC=${NAME//\"/}

if [ `echo $BTMAC | egrep "^([0-9A-F]{2}:){5}[0-9A-F]{2}$"` ]
then
        if [ $ACTION = "remove" ]
        then
                log "Stop Played Connection " $BTMAC
                sudo systemctl stop bluealsa-aplay@$BTMAC
        elif [ $ACTION = "add" ]
        then
                log "Start Played Connection " $BTMAC
                sudo systemctl start bluealsa-aplay@$BTMAC
        else
                log "Other action " $ACTION
        fi
fi

Set the right access permissions:

sudo chmod a+rwx /home/volumio/a2dp-autoconnect
sudo touch /var/log/a2dp-autoconnect
sudo chmod a+rw /var/log/a2dp-autoconnect

REBOOT

After reboot, use bluetoothctl to connect to your bluetooth music source:

sudo bluetoothctl
# power on
# agent on
# default-agent
# scan on => xx:xx of your device
# pair xx:xx
# trust xx:xx
# exit

On your mobile, connect volumio. Should work. Once the device is connected you should be able to play something ...

Checking To check if the services are all up and running: $ systemctl | grep blue You should get something like that:

systemctl | grep blue

Great tutorial! I had to change "/usr/bin/bluealsa-aplay %I -dhw:1,0" to "/usr/bin/bluealsa-aplay %I -D hw:1,0" in /lib/systemd/system/[email protected] to get it working, but otherwise good stuff.

Here is the new one: https://gist.github.com/wolfg1969/32c3798626ad44ffd4c453114a66ffbe
