- decoder: s16 PCM -> stereo int32 -> esp_ae_rate_cvt 44.1 -> 48 kHz (32-bit, complexity 3; bypassed at 48 kHz; mono duplicated) -> ring. esp_audio_effects pinned to ~1.3.0 (1.4+ needs P4 rev >= 3). - hls: each segment is downloaded completely into PSRAM (max 4 MB), then decoded; the connection is not held open while the decoder waits for ring space at playback speed. - player: player_write() blocks while the ring is full and gives up when the source changes; the temporary 440 Hz producer is removed. - Verified with Triple J Hottest: 441344 -> 480375 frames (10.008 s) and 440320 -> 479260 (9.985 s) per segment; RTP 15000 packets, 0 gaps, peak -10 dBFS / RMS -22 dBFS; ring ~4.0 s, 0 underruns over ~50 s; heap 422 KB, PSRAM 27.5 MB free.
