I moved from PulseAudio to SnapCast for streaming audio over my local network as it was easier to configure multiple sinks for multi-room audio.

It looks as though there is support for similar with PipeWire, with the ROC sink and ROC source modules[0][1]. I'm going to have to set aside some time to have a poke around with this and see how it performs.
