If it's literally a copy, shouldn't the copy be pcm_s16be as well? How can I do this and wind up with a pcm copy of the original audio? I've tried -c:a pcm_s16be and it fails.

When asking for support here please provide the command line you tested together with the complete, uncut console output and please do not ask user questions on the development mailing list.
