- audio-bridge: alpine + pipewire + pipewire-pulse + wireplumber + bluez + dbus + tini
Routes audio from librespot/mopidy/phone-BT to USB DAC (Q5K) via ALSA.
Privileged + host network for bluetoothd HCI access.
- mopidy: built from python:3.12-slim-bookworm + pip (no ghcr.io dep).
Qobuz (auth from developer.qobuz.com) + local files. PA bridge to audio-bridge.
- librespot: built from rust:1.85.1 on RPi (cross-compile too slow under qemu).
Spotify Connect target named 'Klubhaus'. PA bridge to audio-bridge.
Both mopidy and librespot build locally to avoid ghcr.io auth/rate-limit issues.
PEQ stays on Q5K side (Qudelix app, 20 bands) for source-independent EQ.
