- main/audio_ring: SPSC ring of interleaved int32 frames in PSRAM (4 s at 48 kHz stereo), lock-free with acquire/release counters; the TX pull callback never blocks. - main/player: source selection from source.mode and the pull callback for aes67_tx. tone -> the core's PTP-phased 1 kHz tone; off -> silence; hls/spotify -> ring with 1 s prefill (silence while buffering is not an underrun; running dry is, and prefills again). Status fields active_source, source_state, spotify_state, buffer_ms. source config applies live. - New source.mode "tone" (validation, UI dropdown, doc) for commissioning. - Temporary 440 Hz producer in hls mode (until the HLS player exists). - Verified: tone 999.7 Hz -18 dBFS; off silent; hls 440.0 Hz with max sample step 60816 (ideal sine 60825, i.e. no discontinuities), buffer 3983 ms, 0 underruns; spotify silent/not implemented.

aes67-ESP32-P4
AES67 sender for the Waveshare ESP32-P4-ETH (PoE): Spotify Connect and HLS/m3u8 streams out as an AES67 multicast stream, PTP-locked, with a simple web UI for settings and SDP export.
