- create systemd service for running pulseaudio: /etc/systemd/system/pulseaudio.service

[Unit]
Description=Pulse Audio
 
[Service]
Type=simple
ExecStart=/usr/bin/pulseaudio --system --disallow-exit --disable-shm

[Install]
WantedBy=multi-user.target

- reload systemd with systemctl daemon-reload
- Give the pulse user permission to use Bluetooth: /etc/dbus-1/system.d/pulseaudio-bluetooth.conf

<busconfig>

  <policy user="pulse">
    <allow send_destination="org.bluez"/> 
  </policy>

</busconfig>

- start the service: systemctl start pulseaudio.service

- enable service at startup: systemctl enable pulseaudio.service

- Paste the following lines to the end of /etc/pulse/system.pa

### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
.endif

.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif

- add the correct permissions for user pi:

sudo gpasswd -a pi pulse-access
sudo gpasswd -a pi audio
