As per anki documentation, you should not use [sound] and [img] elements in card templates. This is unsupported behaviour, and while it works in Linux and (probably) Windows, it is definitely not working in MacOS — sounds are not playing, images are not visible.
Correct solution: both cover image and sound link should be enclosed in respective tags directly in a card fields. I've already verified that this fixes the problem on MacOS.
[ ] update the code and make a new release
[ ] update documentation (card template change)
[ ] notify existing users that they need to change card layout
Exporting sounds as [sound:path/to/123123.mp3] (won't work on MacOS, use anki plugin to download media)
Exporting images as <img src="http://path/to/image.jpg">
