Are you sure it''s ALC255 because on another thread with 3020, it's showing ALC280.

Nevermind, the pdf shows ALC255.

Change layout-id to 13 and and enable FixMutex in your Config

In kexts/Other, remove Shiki.kext, IntelGraphicsFixup.kext, and AzulPatcher4600.kext and replace with WhateverGreen.kext.

Yes this one is ALC255, still unable to get my audio works. Already use the config.plist u given, and delete Shiki.kext, Intel GraphicsFixup.kext and AzulPathcer4600.kext, also install the WhateverGreen.kext. Still no sign of audio. This PC have internal speaker and front audio jack / mic jack  (no rear jack).

It doesn't work. Before this, the internal speaker works on Windows. This PC doesnt have HDMI audio out, just have VGA and DisplayPort. 

Ok looks like AppleHDA does not loads. When i type  kextstat | grep -y AppleHDA  on terminal it shows nothing. And at the System Information/Hardware/Audio/ shows nothing.

 

I already include the files in the attachment. Thanks!
