Error Setting up for audio extraction

I was able to resolve this by expanding the media locations accessible with sandboxing.

I am getting this error with attached XML. Can you suggest how I might proceed?

Writing AAF file
Adding assets to AAF file
Adding essence for asset [P1020436] to AAF file
Opening audio extractor for portion 0 of asset [P1020436]
Failed to initialise audio extractor with default bit depth of 24
Error Setting up for audio extraction (The operation could not be completed)

Suggestion: Does this movie contain an unsupported audio format ?
