I'll explain my situation, so you see where I'm wrong, I install montery just finished, I copy the Efi folder and put it in the efi of the hard disk, then I install nvidia kepler for the gt 730 and everything works, I have seen from aida64 with windows that I have ALC221 , I have tried in every way but I can not show audio, I do not check anything. working audio from windows and linux.
please help me, maybe explain me the steps to take.
