The pull callback's contract said "stream channels", but the player always delivers stereo, so a 1-channel stream went out as L,R,L,R at half speed. Sources now always deliver AES67_TX_SRC_CHANNELS (2); TX maps to the stream: 2 ch as is, 1 ch = (L+R)/2 in 64 bit with mono_sum (can't clip), else L. Checked: mono packets 156 B, 1000/s, 48 samples each, SDP L24/48000/1. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
