Mine is a 13" with two ports, which isn't supported based on the GitHub page.

So you have a MacBookPro14,1, which should support audio output (not input) using the patch linked. There is an AUR package for that audio driver: https://aur.archlinux.org/packages/snd-hda-macbookpro-dkms-git And more info on the drivers github repo: https://github.com/davidjo/snd_hda_macbookpro Good luck!
