OpenCore: Touchpad and Audio not working | Asus Zenbook | MacOS Monterey

[axel2929]

Hey there,

I'm new here, so I'm not really sure, where to put this post. If there is a better place, please tell me or move it.

To my problem: I'm using Mac OS Monterey with OpenCore 0.7.8.

I followed the Dortania Guide, but I can't get my touchpad and sound working.

This is what my EFI/OC folder looks like:

config.plist can be found in attachments:

config.plist

 

Touchpad:

In linux live usb I figured out the type of my touchpad: I2C ELAN1200

So I added VoodooI2C, VoodooPS2Controller and VoodooI2CHID kexts, as ELAN1200 needs HID and not ELAN kext.

But the touchpad keeps not working. So tried hints at this page: https://dortania.github.io/Getting-Started-With-ACPI/Laptops/trackpad-methods/manual.html#enabling-trackpad

VoodooGPIO should be attatched:

As written in "_OSI to XOSI" section, I tried to add to precompiled SSDT-XOSI.aml. I'm not sure if I might need to customize the dsl and compile manually, but I just didn't really understand how to edit the SSDT-XOSI.dsl correctly.

Also I'm not sure how to follow the instructions in the next section "Create OSYS Variable Under I2C Scope".

 

Audio:

Via linux live usb I figured out, which codec i need to look for: ALC 294

I tried all layout-ids that are listed at ALC294: layout 11, 12, 13, 21, 22, 28, 44, 66, 99

But not a single got the audio working. The weird thing is, that sometimes it worked after a reboot from windows (I'm using dualboot with Windows 11), but never after a normal start.

In IORegistryExplorer the audio controller is attached

 

My specs:

• Laptop: ASUS ZenBook UX533FD
• CPU: Intel i5-8265U 1,6 GHz Whiskey Lake
• GPU: GTX 1050 (deactivated), Intel UHD Graphics 620

 

Does anyone know what I could try?

I'd be very thankful for tips!

As far as the Trackpad is concerned: are you sure VoodooInput has to be disabled? Maybe this helps: https://github.com/5T33Z0/OC-Little-Translated/tree/main/05_Laptop-specific_Patches/Trackpad_Patches

You need EFI + Ioreg, the config alone is useless, probably the problem depends on the ACPI

First of all, thank you for your response!

I supposed that not 2 VoodooInput kexts could be enabled, as ProperTree only enables one automatically and both VoodooI2C and VoodooPS2Controller got a VoodooInput plugin.

Nonetheless I tried to set both VoodooInput kexts enabled, but as expected OpenCore didn't start. After that I tried to disable the one of VoodooPS2Controller and activate the one of VoodooI2C. But It didn't work.

I will try this and report my results, thank you for the advice.
