Big Sur update 11.3.1 No audio O.C. 0.6.9

[Dimitar Maratilov]

My hardware is:

Motherboard: Z390 AORUS Master
CPU: i9-9900k
Graphics: RX 580

I updated Bios from f10 to f11n, updated O.C. 0.6.8-0.6.9 including the latest Kexts and I updated Big Sur to the latest 11.3.1

My audio was working fine before on channel 1.

I do have audio on my Windows 10.

I'm not sure the exact moment that it disappeared.

I've started checking the other channels for my ALC1220 https://dortania.github.io/OpenCore-Post-Install/universal/audio.html

I went through all channels and reset the NVRAM each time but the audio is still not working.

I see that O.C. 0.7.0 but I'm not sure this will fix my issue.

I don't know how but the audio started working.

I read from the internet to put boot-args: -alcdbg -v -liludbg -lilubetaall

Cleared NVRAM and the audio started working, I removed these arguments, cleared the NVRAM and the audio is still working.

I don't know what happened but I'm happy now

I went to Windows and now is gone again will keep looking for the issue.

I found that when I execute: ResetSystem.efi after switching to Windows the sound is here.

How do I bypass this without Resetting the system?

I deleted the Realtek Audio Driver in my Windows and now everything is back to normal.

It was installed via my Gigabyte Update center, and this is why it coincide with the Bios Update.
