WirePlumber is completely overkill as a session manager here, and ideally a trivial session manager would be used instead. I did build a Spectrum OS image and found that PipeWire and WirePlumber both successfully started. PipeWire is configured to listen on the PulseAudio socket, so PulseAudio compatibility works. This does inject a large number of completely unnecessary files into the VM, notably for libcamera and Bluetooth support.

Notes: I tested this with QEMU virtio-sound, but I am not sure if the paramters are correct. In particular, the sample rate might well be wrong.

The PipeWire and WirePlumber config files are still very big. Is it really not possible to make them smaller and rely on defaults where possible? With a whole big config like this, it's difficult to see what Spectrum-specific stuff is going on.

Do these all conflict with PipeWire/WirePlumber/PulseAudio??
