Direct Play of any (E-)AC-3 track on Apple TV developed persistent
micro-stutter: mpv's audio clock was derived from es_pts on the
compressed path, which is credited a whole 32 ms burst the moment a
payload lands, sawtoothing the clock on a ~0.8 s cycle that video
retires as visible skip/hold pairs. AAC content was unaffected, which
is why the symptom tracked Dolby audio and survived every VO-side fix.
MPVKit 1.0.23 measures the clock from IEC samples actually handed to
ao_read_data instead. Verified with an HDMI capture rig against the
CI-built binary: EAC3 display cadence is now statistically identical
to AAC (was 47.6 skips/min plus 453 multi-frame holds over 38 min).
