Is CFG Lock in the bios unlocked or locked?

hi your EFI try https://easyupload.io/ozwyve

Have you added your layout in boot-args alcid=.......? https://imgur.com/gallery/R4lFmV8

👍 if you want now you can go back to using opencore, or try updating the kext ALC , LILU .......etc https://dortania.github.io/builds/?product=AppleALC&viewall=true&version=1.6.2&sha=9d726f6902f0768b7ee08c7dde6171d0181a3682 always select the latest vers. and release try to change layout if that's the case

Certainly try to bring the configuration you have in OC to Clover, I finalized the update on the first try 🤞

Unfortunately many are unable to update with OC and the reason has not yet been understood well, I myself have overcome the problem of the macintosh hd loop with Clover by finalizing the update I suggest you download the Monterey beta 2 directly, create the usb installer and install from 0 by formatting the harddrive https://swdist.apple.com/content/downloads/54/23/071-59953-A_U9D4NB05NR/nqzt71pnylsuux326a4vqexb33oz0auhas/InstallAssistant.pkg

RealtekALC887 0x100202, 0x100302, layout 1, 2, 3, 5, 7, 11, 12, 13, 17, 18, 20, 33, 40, 50, 52, 53, 87, 99 you have other layouts to try

try to change layout in boot-args alcid = xxx if you know which codec you have (check your codec with hackintool) here is the list of layouts available for each codec https://github.com/acidanthera/applealc/wiki/supported-codecs take a look here too https://www.olarila.com/topic/6074-guide-easy-audio-solution-with-applealc-clover-and-opencore/
