Alpine's pipewire-pulse package ships the daemon binary but doesn't auto-load the PA bridge module on alpine. We need to start pipewire-pulse as a separate process with -a tcp:4713 so PA clients (librespot, mopidy) can connect via TCP. Layout: - pipewire: audio server (native protocol) - pipewire-pulse: PA-compat bridge, listens on tcp:4713 + unix:/tmp/pulse-socket - wireplumber: session manager (loads BT modules, hot-plug handling)
