playback noise from a nested no audio clip
A segment of nested time-lapse clip has high pitch ringing sound overboard.
but it's a silent clip originally, doesn't even have audio track
Playback in the nested sequence / original is totally fine.
but the parent sequence have noise while all the audio filters were removed / all attributes were reset,
a certain part keeps ringing. I cannot even understand how can this happen when you have a no audio clip to start with.
