No Audio Devices - Realtek ALC AppleHDA [Guide]

[tbjem0013]

I have a Gigabyte 100 series GA-Z170X-UD3 motherboard. If it's unsupported there is nothing I can do but get USB or HDMI audio?

After updating to 10.11.6, I had no audio device anymore (ASUS Z170 Pro Gaming, ALC1150 codec).
Using Toleda's instructions in No Audio Devices, as well as Audio, using Clover, it's back.


Thanks a lot for this guide, Toleda!

Motherboard: Gigabyte B75M-D3H
Audio: Realtek ALC887
Mac OS: El Capitan

I recently upgraded from Mavericks (Chameleon) to El Capitan. The network is working without any intervention of Multibeast. But, in the audio, I cannot see any devices under the Output section. This is a fresh install. I had earlier tried using Multibeast with different kexts, but nothing seemed to work. So I reinstalled the OS in the hope that a clean slate and with the advice of good people here, I'd be able to diagnose and resolve the issue.

Any help will be much appreciated.

That's great to hear. There seems to be a multitude of ways one can go about. Can you please guide me as to which way proved successful for you?

The guide under post #1 of this thread was a bit overwhelming for me at first, but ultimately it's doable if you do it step by step. I'm using Clover, so I chose that method. You really need all the tools described to diagnose the problem. Then you do the steps listed under I.

Problem:
symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795>
Not an audio problem, a system problem. May require a fresh install. Off topic.

1. No sound device. I did a fresh install but the same problem. In the same computer , in different hdds have El Capitan 10.11.4 with sound, Windows with sound and Sierra 10.12.3 without sound

Toleda thanks for your help. I have executed in the terminal your command but there is the same error. Please find attached the log . I have cloned the disk in other external disk using USB and there is sound with the same data , the same clover etc. It is very strange.

 

[toleda]

same error

Suggest an install over the existing install.

IOReg shows audio is working.

Audio is working with the black rear port, not the green one...

Las time you said:
Script:
Install /Library/Extensions/realtekALC.kext
Install System/Library/Extensions/AppleHDA.kext/ALC1150 zml files
The script did not remove the file it installed.
Run the script again.

I run the script again, and the shell info is the same, I don't have any realtekALC.kext anywhere, and you said the pin configs are installed with realtek command and I want to fix it, because I'm working now with cloveralc command and the black read port is the only one that works.

Can you help me or not?
