<< Solved >> Monterey crash/freeze ALC1220 audio problem

[artroeb]

My problem is only in the audio. Asus Strix H470-I - ALC1220 only works with FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext but it make a crash, without the kext fix the crash but audio doesn't work.

Can someone help me?

i tried one by one id for alc1220, add layout id in device properties, add alicid in nvram boot args still audio doesn't work.

Solved with:

- Remove FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext.
- Remove device patch for audio on device-properties and add alcid=# on nvram boot arg.

hi, could you tell me more on how to remove device patch? is it on config.plist? thank you.

Yes.. if you add PciRoot(0x0)/Pci(0x1F,0x3) device-properties path on config.plist delete it, then add nvram boot-args alcid=7 in my case.

Find your support codecs for your audio.

You will need to add your system information to your profile. Entering "Intel" in all fields (as you've done) won't do anything to help you.

You might also try placing layout-id 7 in DeviceProperties instead of putting it in boot-args. It's much cleaner (if it works). Cheers.

Actually it's true Audio doesn't work if we add device-id, just remove device-id on DeviceProperties and audio will work.

But this doesn't work for HDMI audio on iGpu. If some people need audio for HDMI they should add FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext with the problem freeze.
