Audio Router

This daemon owns the physical PipeWire/JACK links for sanctuary audio. MQTT topic names and payloads remain under the existing audio/player base topic.

YTPlayer audio follows one path:

MPV -> ytplayer_bus -> Audio Router -> HDMI, analog, or disconnected

The virtual sink definition lives at pipewire/20-ytplayer-bus.conf. Install it as ~/.config/pipewire/pipewire-pulse.conf.d/20-ytplayer-bus.conf; PipeWire Pulse will recreate the bus after restarts.

Preset policy:

  • service: mixer to HDMI only; YTPlayer disconnected
  • video: YTPlayer to HDMI
  • announcements and aux_only: YTPlayer to analog
  • mute_all: YTPlayer disconnected

The router starts muted, restores the retained audio/player/mode/state once, and periodically reconciles missing links. YTPlayer is configured as an exclusive source, so a preset that enables both HDMI and analog is rejected.
