@chriz74,

 

Internal Mic = 8-35-25

Internal speaker = 20-13-3

HeadPhones = 26-12-2

 

Hereattachicon.gifArchivio.zip, personally I'm sorry but I'm not going to analyze the files of each and every one of you, just grab a fixed and make a comparison.

why i can't download this file?

@Mirone

Hello… Im starting to read about AppleHDA binary patching and I'm curious about one thing.

vanilla codec that can be replaced by our own codec can be one of the  following:

8b19d411
8408ec10
8508ec10

Which of those do you think is the most proper one to be replaced?

Hey Mirone,

 

Can the AppleHDA patch be applied by using Clover?

 

If so, how would one do it?

 

Thanks

Hi Mirone,

 

I had tried ur manuals untill -changing platform.xml.zlib- step. Then I got stuck, bcause I really can't understand reading the codec-dump-dec.svg & decide which node should I set in platform.xml.zlib.

but, it's okay. I'll keep trying.

 

I want to ask this first,

the hesitation comes up since chapter 2 : CORRECTION APPLEHDA.KEXT

I want to ask about, which AppleHDA should I used to patch? Vanilla, or from ur kext patched already?

 

fyi, I'm using Realtek ALC233 now. Tried using instant way both clover & dsdt, with both layout 3 & 28, the problem is still, mic can't work (hapened in layout 28), & when using headphone, the sound is really bad with balance setting, and in order to be clear, I have to set it to full right/left balance in sys pref (happened with both layout)

 

and last question,

If I need ur help, so I have to send u my codecgraph folder (with codecdump inside), or is there anything else??
