- main/audio_out: one converter instance per source (own rate converter state): s16 any rate/channels -> 48 kHz stereo int32 -> ring. - player_write(src, ...) only writes for the active source, drops the rest; player_src_t is public in player.h. - HLS decoder uses audio_out (no behaviour change). - Verified: HLS still sample exact (441344 -> 480375 frames per 10.008 s segment), buffer ~4 s, 0 underruns.
