I am on 2.7.6.
I want to use Avidemux to rotate a 20s .mov file. I am able to rotate it successfully and output to a file. However, the audio isn't saved or copied over. I tried many permutations of Video Output/Audio Output/Output Format, but no joy. One configuration that works, but no sound, is:
Video Output: Mpeg4 ASP (xvid4)
Audio Output: MP3 (lame)
Output Format: Mkv Muxer
What could be a set of parameters that will work for my situation?
My Edit/Preferences/Audio AudioDevice is on Win32.
Version 2.7.6 is very old. Latest nightlies are available below:

Actually, you can set rotate flag (90/180/270) in container options and set both streams to copy. The container must be MOV or MP4. If it is not enough, you'd better recompress video with AVC (x264), set audio to copy.
What is the "container" you are referring to? I can't seem to find it. Thanks.
Video Output is the encoder for the video. Mpeg4 AVC (x264) will produce a h264 video stream.
Audio Output is effectively the same as above, but for the audio stream.
Output Format is your container. MP4. MKV, and MOV etc are container formats that contain your video and audio streams.
They do a lot more than just contain the streams, but you'll need to google and read to get a greater insight, if you want to learn more.
If you choose MOV, or MP4 you can select the Configure button under Output Format and there is an option to Rotate video. No encoding is required.
