While playing with options on a simple light/dark test, I discovered that the audio cut out halfway through the video.  Upon further inspection, I noticed that the logs were indicating a sync issue.  I verified that the problem exists with 3 audio options:
--audio-codec MP3
--audio-codec faac
--save-raw-audio

The specific command-line was:
$ avidemux_cli --load in.mov --save-raw-video --save out.avi --save-raw-audio
...
[ODML]write dummy chunk at file position 235492 with data size 131072

...
It continues to drop audio packets until the end of the file.

The only mention in the internet seems to be the source file: ttp://tinyurl.com/m3zjj9z
