I'm glad that BigSur was successfully installed, but there is a small problem. The rear onboard audio is all right, but the onboard microphone doesn't work. I tried to inject all the sound card IDs, but it still doesn't work. My sound card model is ALC1220. Can you help me? Thank you very much! ! !

Onboard Mic doesn't work on AMD with AppleALC. It may be possible to get it working by creating a custom layout but the documentation isn't great.
