WirePlumber 0.5: Bringing Smart Audio Filters to PipeWire
summary
WirePlumber 0.5 adds smart filters that automatically attach PipeWire filters by matching a filter target and ordering with before/after properties; configuration moves to JSON and can be changed at runtime via metadata. A concrete example: WirePlumber creates a loopback source filter per Bluetooth headset, hides the real HSP node, and switches the device profile to HSP when any client starts capturing from that loopback, then switches back when capture stops — demonstrated working on 0.5.1 with Arch Linux.
