Hi guys i just installed Catalina using Open Core. Everything is working except audio. I tried to install the os multiple times chaning some parameters but nothing.
I followed this guide: https://khronokernel-2.gitbook.io/opencore-vanilla-desktop-guide/

I'm pretty sure the problem is here:

Maybe i'm setting a wrong layout-id? Am i missing something?
I tried different layouts (1 and 11) (the one in the picture above is 11) https://github.com/acidanthera/applealc/wiki/supported-codecs
Here's the content of the USB:

And here's the config.plist i'm using https://pastebin.com/2QBpqafb

My hardware:
CPU: intel i7 8700k
GPU: integrated intel hd630
RAM: Corsair ddr4 16GB (2x8)
Motherboard: ASUS ROG Strix Z370-E -> Audio: Realtek S1220A

Any help is much appreciated :3

What's stopping you from trying out other layouts?

One thing strikes me though... Are you sure your HDEF (or whatever name) audio device is located at 0x0b, not 0x1b ?

 

Is there a way to try other layouts without reinstalling the OS from scratch?

 

Also i'm not sure about the 0x0b, how can i check it out?

Does

 gfxutil -f HDEF 

works also if audio is not working?

Sorry but i'm kinda a noob

Where i can find the config file?

 

Here's what i found about HDEF in the register

I also attached the ioreg output

As for the DSDTs i used mine without modification generated with SSDTTime

I got it! The config file on the USB, i tought i had to edit a file on the harddisk

Anyway the correct address was 0x1f 0x3

Thanks :D

How did you figure out it was 0x1f 0x3?  I'm having the same issue with similar specs.   Not sure where to look or what to change on the config.plist
