@soeryobadja For me, the audio also gave a massive headache back then I tried to configure it. I am using Clover tho. I had to enable FixHPET, AddMCHC, FixIPIC, FixMutex, FixRTC, FixTMR, and using LayoutID = 32. After that, the sound and microphone started working.
The last thing is the jack, I am using ALCPlugFix for that but it is really buggy, most of the time it doesn't work at all. I see that on the newer version of AppleALC there is an "alc-verb" binary in the release, I tried to use that but it doesn't work.
I think on OC you can use
SSDTTime to create the SSDTs, reflecting the fixes above (except AddMCHC)
