[Help] AppleHDA patching

[EverythingIsRed]

I tried using Mirone's AppleHDA Patcher for my Connexant onboard audio (codec: CX20756) but it doesn't list any audio I/O devices after installing. I'm guessing it has something to do with the kext's compatibility with Sierra?

Can someone help me with patching AppleHDA? I've attached codec dumps from linux in case anyone wants to have a look.

I've patched DSDT with "Audio Layout 3", "IRQ Fix" and added a DTGP method. The AppleHDA patch was done using Mirone's AppleHDA Patcher.app.

Still can't see any audio devices.
Files attached.

Now layout-id is being injected (as 3). You should check your AppleHDA.kext to see if it actually uses layout-id 3.

It is covered in the ACPI patching guide.
