Kernel panic when use microphone, for example facetime.

It works well before big sur.

 

Any ideas?

 

Motherboard: epc621d8a

CPU: intel gold 6278c 26c52t

 

There was a similar problem with microphone using VoodooHDA. I fixed it in VoodooHDA 2.9.6. But I don't know who will correct AppleHDA or is it possible to correct AppleALC.
