Hello! I need your help.

 

I have Big Sur installed Using Opencore 0.7.2 and everything works fine Until I Update The Lastest Big Sure 11.5.2. When Update Finished No Output And Input Device For My ALc892. but HDMI Audio WorkFine. 

I'm using AppleALC.Kext + Lilu but and test any Layuot ID number  for Alc 892 it doesn't work too.

I've try Fix using SSDT HPET it same too. 

 

I would be immensely grateful if anyone can provide a solution!

Please complete your signature (user >> profile).

 

Try deleting audio entry (PciRoot(0x0)/Pci(0x1B,0x0)) from DeviceProperties and adding alcid=3 in boot-args. 

I've test That. Still Not Working. when i change the layout number it change the output and input device on HDMI Audio. but still no audio device on my Alc 892.

Try alcid=99 in boot args

OR

Remove alcid from boot args, add (PciRoot(0x0)/Pci(0x1B,0x0)) to device properties with layout-id 63000000

OR

Remove alcid from boot args, remove applealc kext and add voodoohda.kext

It means you haven't installed the correct driver. This also happens in windows when wrong driver is installed.

I'd suggest to remove voodoohda and add applealc and try each codec number one by one and see which one works. If none of the alc892 codec works, you have no option other than going back to voodoohda. Maybe ask in those forums.
