I've followed your advice to use Vanilla Installation, tried all the advisable EFI given here but it seem I can't make it work my audio.
My kext are updated.
Currently running Mojave 10.14.6. Hope you can help me.
Update:
found a solution, its not AppleALC.kext but VooDooHDA.kext. now my audio is working.
