How to add audio to video using ffmpeg on Linux?

Question

I am able to do this just fine on Mac and Windows, but seem to be getting an error on Linux:
Command Failed: ffmpeg -y -loglevel warning -hide_banner -nostats -strict -2 -i "/home/runner/work/stone/stone/build/mount.quiet.mp4" -i "/home/runner/work/stone/stone/build/crow.wav" -shortest -c:v copy -c:a aac "/home/runner/work/stone/stone/build/mount.crow.mp4"
Guessed Channel Layout for  Input Stream #1.0 : stereo
[aac @ 0xdfa9a0] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

What encoder should I use instead to get this working?

Your ffmpeg must be very old to need -strict for AAC encoding. Unfortunately, -hide_banner is hiding the version and other info.
You have two ways to fix this:

Option placement matters. You're using -strict as an input option. Move it so it's after the inputs so it is an output option.

Update to a modern version and you won't need -strict. I recommend this solution. For Linux yo can download a static build from johnvansickle.com (see FAQ for install instructions).
