Home Server as Bluetooth Speaker

Two machines: Server and Media Player

On Server:

• Requires pipewire, wireplumber, bluez
• Related Resources:
  • Bluetooth Class of Device Generator
• Edit /etc/bluetooth/main.conf:

[General]
# Turn server into a speaker
Class = 0x200428
AlwaysPairable = true
ControllerMode = dual # default

# optional but I did it anyways
Experimental = true
KernelExperimental = true

• Make sure wireplumber is up, and wpctl status can see that there's a sink.
• In case wpctl status shows no sink, plug in the audio output device and restart pipewire

systemctl restart --user pipewire.service

• Run bluetoothctl and set the following varibles:

bluetoothctl
[server] power on
[server] agent off
[server] agent NoInputNoOutput
[server] pairable on
[server] discoverable on

• Now, on media player device, connect to the bluetooth server. It will show the device as a speaker.
