5.1 surround network speakers appear as stereo on client system
My 5.1 surround speakers are connected to a Raspberry Pi which is configured with a PulseAudio server, and PipeWire on my laptop and desktop connect to that using the zeroconf module. After a few issues have been resolved in the past, this now works well enough to use as a daily driver setup.
However the only remaining issue now is that the speakers only appear as stereo on the clients. When I switch back to PulseAudio it sees it as a surround setup and shows all the channels rather than just the two, but when I then switch to PipeWire again it's back to stereo.
