Dell Vostro 5568: freeze on wake & no headphones - Big Sur in Other Dell laptops Posted Saturday at 04:43 AM · Report reply Dera @fndklm Yeah. Just remove those entries. I may have missed it. Had to remove my usb drivers kexts from the EFI folder for posting. Regarding the audio issue, apparently it could be an issue with the patched AppleALC.kext. Will need to investigate this further. Cheers!
