Summary of the bug: If you have a quicktime mov with audio as a stereo pair and is assigned as Left Total Right Total, export wav audio with ffmpeg produces a wav which wont play in Quicktime or Final Cut.
How to reproduce: If you have a quicktime mov with video and audio, the audio is a stereo pair and is assigned as Left Total Right Total. To assign audio open the quicktime mov in quicktime pro, 'Show Movie Properties', select Sound Track, 'Audio Settings', 'Assignment', use drop-down to select 'Left total' 'Right Total'. Using the command below produces a 24 Bit wav which wont play or open in Quicktime or Final Cut. If you create a 16 Bit wav then it plays fine.
