Ubuntu Version:
25.10 Server on Raspberry Pi 3B

Problem Description:
I want to set up this Raspberry Pi as a Bluetooth audio device (an audio sink).

I am using PipeWire and WirePlumber.

I can connect to it with Bluetooth, but it doesn’t appear or behave as a device that can receive audio.

I believe that the issue is that WirePlumber is failing to register a sink endpoint (A2DP, with a 0000110b UUID) with Bluez, and I think it’s because the PipeWire Bluetooth discovery module is not properly installed.

What discovery module do I actually need, and which package contains it?

Hi,

Unfortunately, I know absolutely nothing about this subject.

However, I believe @waveform might be able to offer some suggestions.

Hope this helps.
