debug("GetAudio: %d,%d", start, count);

Dont use %d for __int64, use %I64d, or results will be wrong:- https://docs.microsoft.com/en-us/cpp...s?view=vs-2017

does this mean there's something between calling child->GetAudio

Well there is some stuff in source about audio cache, but no idea how it works.

enum {
  CACHE_NOTHING=0,
  CACHE_RANGE=1,
  CACHE_ALL=2,
  CACHE_AUDIO=3,
  CACHE_AUDIO_NONE=4,
  CACHE_AUDIO_AUTO=5
 };

EDIT: Oops yep, %I64d or eg %I64X.
