<< Solved >> No Onboard Audio on Asus Prime Z370-A (Monterey)

[hackeron]

Hi there,

My onboard audio on the Asus Prime Z370-A is not showing up in Monterey (it was working on older versions of MacOS). I have tried:

Download and install ( drag & drop ) in EFI / Clover / Kexts / Other folder:

1. AppleALC.kext
2. Lilu.kext

Edit config.plist with Clover Configurator:

• Devices / Audio Inject= 1
• ResetHDA = True (checked)
• Acpi / Fixes / FixHDA = True (checked)

I have also tried passing alcid=7 as a boot argument documented here (note I am using Clover though, not OpenCore as despite a lot of effort, I could not get it working with my Sapphire RX580 graphics card).

I have also tried placing AppleALC.kext into /Library/Extensions, making sure permissions are correct:

• cd /Library/Extensions
• sudo chmod -Rf 755 AppleALC.kext
• sudo chown -Rf 0:0 AppleALC.kext
• sudo kextcache -i /

Any ideas what I am doing wrong or what to try next?

Ah, crap, I had a previous version of AppleALC in the EFI drive I was booting from, upgrading from:

```
$ kextstat | grep -E "AppleHDA|AppleALC|Lilu"
Executing: /usr/bin/kmutil showloaded
No variant specified, falling back to release

```

To:

```
$ kextstat | grep -E "AppleHDA|AppleALC|Lilu"

Fixed the problem!
