Mix 5.1 Audio Down To Stereo With ffmpeg

December 2023
ffmpeg -i input.mkv -af "pan=stereo|FL=FC+0.50*FL+0.30*BL|FR=FC+0.50*FR+0.30*BR" -c:v copy output.mkv

This can help if you only listen through stereo speakers and the dialog is mized for a 5.1 or 7.1 or whatever setup.

I haven't tried this on, but keeping it here for reference so I don't lose it when I'm ready to try it
