WirePlumber 0.5: Bringing Smart Audio Filters to PipeWire
summary
WirePlumber 0.5 introduces smart filters that automatically attach PipeWire filters (echo cancellation, noise reduction, loopback) using JSON-configured properties like filter.dosmart=true, name, before/after and target. It creates one loopback source per Bluetooth device, hides the real HSP/HFP nodes, and switches Bluetooth profiles to HSP when a client starts capturing and back to A2DP when it stops. Demo on Arch (0.5.1) shows the auto-switching works for multiple devices without per-app hacks.
