Settings → Audio can pick start/stop cues from the shared catalog (lift, flick, ember, step, voca, soft, chirp, scale, drop, glass, off). New installs and any missing or unknown sound_effects.tone value use voca. A saved id, including off, is left alone. The old start_recording/stop_recording files stay on disk. They are no longer the implicit default. Error cues still follow the existing enable switch.
