Help ?

Hello everyone,

I managed to successfully install macOS Big Sur on my hardware, however, I cannot get the audio to work (I tried every layout and fixing IRQ conflicts), any ideas why ?

​

CPU : Intel Core I5-2400

GPU : AMD RX 550

RAM : 8gb DDR3

Audio : ALC662

Here is my EFI https://drive.google.com/drive/folders/1bk8l-tF6LleU_VckmftW2huN76dkkUnO?usp=sharing
