audio: select the pipewire backend explicitly and ban the pulse one Full-system audit findings: without an explicit provider selection the image installed real PulseAudio (Plasma Mobile hard-path), which claims the card and ships a wireplumber fragment disabling hardware.audio - zero sinks forever. Mirror the dev phone's world: pipewire backend meta + pipewire-pulse + echo-cancel in extra_packages, pulse meta banned via apk conflict in fp6-device-tweaks. The two hand-made /etc audio fragments (wireplumber no-ACP rule, AEC pair for VoLTE speakerphone) move into soc-fairphone-fp6-audio.
