The ADSP front-end advertises S24_LE and then garbles it: playback runs without an error, consumes data at rate, powers every DAPM widget, and produces ~-48 dB of near-silence. PipeWire prefers the widest advertised format, so every PipeWire client was inaudible while aplay and speaker-test, which default to S16_LE, worked. One wireplumber rule pins the format until the q6asm handling is fixed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011XgGF5wfxLDAybVnNz6eNQ
