Macbook Pro 2020 2 Thunderbolt 3 ports no audio

Installing Zorin OS

Well hello,

since my macbook is getting a bit slugish, I wanted to test if its the 6 years old Hardware, or a lack of optimisation from Apple to "encourage" me to buy a new M-Series Laptop.

Well - as the title says - I am stuck at getting the audio working. I only have the dummy output available. I already followed the T2 Help article, but that didnt solve the issue.

I got mouse, keyboard, Bluetooth and Wifi working so far, its really just the audio missing. Anyone an idea how I should continue from here?

Hi, I would take a look here:

Found that too. Unfortunately I don’t even get that far. I only get an entry for the Intel Kabylake HDMI

Your Apple doesn't have an M-Chip, right?
