The module can:
- Make a sink that sends all or some channels to other sinks.
- Make a source that combines multiple sources into one.
The selection of what streams to combine is implemented with rules so
that the selection is very configurable. By default all Audio/Sink or
Audio/Source nodes are selected.
Add a module for a fallback dummy sink, which appears dynamically when
no other sinks are present.
Enable it for pipewire-pulse, because Pulseaudio will also show
dynamically a dummy sink.
I don't think PipeWire currently has a way to temporarily alias
module-rtkit to module-rt though, so right now this would break realtime
scheduling for people with modified configs that use module-rtkit.
