Help needed with ALC272 Audio to work in ElCapitan Installation

[rox_rahul@ymail.com]

I have refered https://github.com/acidanthera/AppleALC/wiki/Supported-codecs to get the layout id for the audio codec ALC272 used in my laptop. How ever, I have tried both the layout ids mentioned there (3 & 11) but Audio doesn't work.

1. Use clover folder attach and boot.

2. For sound, inject correct ID in clover. Currently set at 3.

3. Use SMbios MBP 8,1

4. Submit new send me file.

1. I have replaced the the Clover folder with the one you have provided.

2. 3 & 11 are the correct layout id for ALC272 Codec. Now I have set to 11.

3. I didn't understand this "Use SMbios MBP 8,1"

4. Yet to do...

please reply.

 

Choose SMBIOS via clover configurator

Done. Most my settings have reset after restart, like tap to click, etc. Hope everything is going normal.

[ref]rox_rahul@ymail.com[/ref], Layout ID is injected correctly. However, AppleALC kext does not seem to be loaded. If you had voodoohda or patched AppleHDA in S/L/E (or installed using kext utility) you must remove them or revert to vanilla AppleHDA.

If the above are all in order, you can try previous releases of AppleALC prior release 1.3.0. This is true for me in Sierra where release after 1.3.0 did not work.

it helps to repair permissions and cache.

Let me know your progress.

PS: Use DSDT attached and check brightness hot keys if its working.

EDIT: Your laptop need not use USBInjectall.kext. You can remove it.

Previously I had just installed VoodooHDA in Kexts/Other folder, which is removed. How do I restore the vanilla AppleHDA kext ?

How do I restore the vanilla AppleHDA kext ?

Just reinstall without formatting system drive

[rox_rahul@ymail.com]

Well, just after I read your comment, I installed Pacifist. But When I clicked it to run, the system hanged. And I turned off my machine by pressing power button because there was no option (Many times I have to do this when system hangs.) Now before I could proceed to restore the AppleHDA, I found that the Audio is actually functioning properly. I don't think I need to restore the AppleHDA I guess, I didn't make any changes to it, and my Sound is actually working fine without any problem.

Good to know. Did you test brightness hot keys?

[rox_rahul@ymail.com]

Oh I almost forgot! Yes, Brightness hotkeys are working flawlessly. Thanks for the DSDT. Should I consider my Hackintosh stable or nearly stable now ?

[onemanosx]

[ref]rox_rahul@ymail.com[/ref], Just use it normally. Do take note, sleep function may or may not work in hackintosh. So, dont have to be alarmed about it.

Anyway. upload new send me file for checking.
