No Audio Devices - AppleHDA Realtek Audio

[maxix1234566]

Please tell me how to start the sound on codec ALC662 in Big Sur, everything worked in Catalina, I decided to upgrade to Big Sur and how I can't get the sound

I've been with VoodooHDA and AppleALC - it doesn't help, if you use VoodooHDA then HDMI ports appear, but there is no built-in sound card, there is not a single device with AppleALC

Spoiler: audio

Tried all the identifiers supported via boot-arg: alcid=

I checked the correct loading of the castes

In ioregistryexplorer, if you look at that alc-layout-id is set

Problem solved!

If anyone is interested: I found and removed the file HDAEnabler1.kext from /S/L/E and all of my audio problems have resolved. I'm not sure what that file was for or when I put it there... I'm guessing from a previous audio fix.

This worked for me too! Thanks, thanks thanks thanks! I must have wasted 20-30 hours trying to get my audio ALC898 (GA-Z77X-UD5H) to work after high sierra to mojave upgrade. This should be made an item on the front page with the main instructions. I am sure this was the problem for many folks!
