I have this same condition and have not found a solution. This applies to audio files from Zoom H2. My typical setup involves 2 cameras (Panasonic af100 and gh3) with 1-6 H2’s collecting audio throughout a room…I’m shooting professional development in a classroom environment. Typical workflow is place video and external audio tracks on a timeline and use the Pluraleyes app to sync everything via audio. If the project is on any external USB drive 2.0 or 3.0 the audio from the H2’s will have this condition. Only was to solve it is to put the H2 files on an internal drive. This a waste of my time Sony! It’s been a problem since Version 10, at least that’s when I discovered it.
I’d love to get this conversation active again.
