<h4>audiohook.c: Improve frame pairing logic to avoid MixMonitor breakage with mix..</h4>
<p>Author: Michal Hajek
Date: 2025-05-21</p>
<p>This patch adjusts the read/write synchronization logic in audiohook_read_frame_both()
to better handle calls where participants use different codecs or sample sizes
(e.g., alaw vs G.722). The previous hard threshold of 2 * samples caused MixMonitor
recordings to break or stutter when frames were not aligned between both directions.</p>
<p>The new logic uses a more tolerant limit (1.5 * samples), which prevents audio tearing
without causing excessive buffer overruns. This fix specifically addresses issues
with MixMonitor when recording directly on a channel in a bridge using mixed codecs.</p>
