It was set up display-only, with alsa_device "simulate", so the UI showed a working player that made no noise - but the Pi has a HifiBerry amp and pi_alsasetup already put the softvol_effects slot on it. Point the backend at it, the same way musicmouse does: a softvol control feeding dmix, so the card stays shared with squeezelite and shairport instead of being locked. Carry musicmouse's volume clamp over with it. Below roughly 23 the softvol attenuation leaves nothing audible, and the ceiling keeps a UI slider from putting the amp to full. Those numbers are tuned to musicmouse's speakers and this is a different room, so they are a starting point. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# musicdolphin: screen-driven instance. No physical mouse is attached, so serial stays

# "simulate" and the web front-end (shown locally in the pi_kiosk Firefox window, and
|
|
# reachable on the LAN for a tablet) is how the player is driven. `figures` still needs
