As I said before, I export the audio and reimport it to solve the issue.

I have indeed worked around the problem by transcoding, but now I know that there is something bad going on. It's not merely a bug or limitation. Avid is adjusting the audio (at least for AMA playback). If it is also doing this in import/transcode, I might not see this immediately. I don't want this to bite me in the butt later. Normally if the audio is short, it just stops before video. 

Has anyone ever seen mismatched video/audio duration in camera original before and measurable in frames?  

I am never satisfied with workarounds. I want to understand. Is this a error in the way AMA is working now, or is a more serious problem with the files themselves. That second possibly is concerns me most. Will I see this problem in the future with any files from a Sound Devices recorder? That would be surprising... and bad since we use them about half the time. Or was the recorder doing something wrong.
