Xenophage , thanks for information.

I tried to dump with ubuntu latest version, it didnt work 5.1 with ubuntu and I setup the realtek driver than the 5.1 output works.

after getting dump , I used taruga 1.20 patcher but it didnt solve my problem , I am currently using LS8v14 kext. bu it has only 2 output.

on the otherhand, ALCinject doesnot work for me. I can just use HDAenabler.kext then this time it is working.

What can I do in this case? Do I need to add efi key and how can I do that.

I have efi studio but I dont know how?
