Thank you for checking this out! Yeah, unfortunately the BIOS is super simple, just has "Audio Controller" and definitely enabled.
DCPI Manager shows 2 audio devices when the Audio Controller is enabled, and 1 device when it is disabled...

Edit #1: The 2nd Audio device is the HDMI audio.

Edit #2: I added AppleALC.kext and CodecCommander.kext to EFI/CLOVER/kexts/other, result is that both devices are identified with a Codec ID, Revision, and Codec Name, but the Codec Names both have (Unknown);

Edit #3 [AUDIO SUCCESS]: Based on another build here on the forum with same MOBO, I added HDMIAudio.kext to EFI/CLOVER/kexts/other and the MOBO audio started to work; not sure if that helped or if 2nd reboot did it. Still testing (carefully) and logging everything in screens and paper..

Thanks, but checked that the on board audio is enabled in BIOS.

Tried differnt methods but dont work. Thanks

Hi guys,

I have a quick question, I did not find any tracer of the Realtek ALC 886 codec.

Do you know if this thread is working on it ?

Or do you know something about this codec ? I don't find any trace of it.

Thanks guys

Hi everyone,

I'm trying to get on-board audio (ALC887) of my B360 board working under High Sierra 10.13.4. None of the described methods work - no audio devices shown in system profiler or system preferences. cloverALC does not detect a codec. The Kaby Lake audio controller patch does not help.

I guess that Intel changed the HDA controller (at least the id) in these new "real" 300 series chipsets. Does anybody know if this can be fixed and how?

Installed multiple 1220 audio methods and multiple HDMI audio methods. Remove all installed audio methods and restart.
Install one 1220 method, reply with new files.

Hi @toleda, here are the new files after your instructions. Audio is still not working.
It's strange, when I restart after running your audio_cloverALC-130_v0.5.command and restart, the audio works but the nvidia driver doesn't get loaded. I'm forced to reinstall the nvidia drivers with SIP enabled to get the GPU working and again, after restart the audio is gone. Mystery...

Hi @toleda - thank you so much for all the hard work you do!

I’ve run cloverALC, multibeast, tried to refresh everything and try again. I just can’t get audio to show up.

I’m starting to realize that somehow I’m having kext injected somewhere in some way that I can’t seem to pin down after re-reading the boot log. I can't even find where they've been placed in the sys!

I imagine that what I might need to do is just do a clean reinstall.

This is my first hackintosh so I’m sure it’s a rat’s nest of the worst practices. Any help you can give me please would be great!

Howdy!

1. Description of Problem: Fresh install of 10.13.4 on a machine that has previously run older versions of OS X. Upon initial boot, no output devices are found in System Preferences>Sound>Output, and as a result there is no sound. Problem persists after many troubleshooting steps were attempted (see #3).
2. OS X 10.13.4/ASUS Sabertooth X79/BIOS Version 4608 x64/Intel i7 4930K/Nvidia Geforce GTX 780 Ti
3. Troubleshooting steps taken: Attempted to use multibeast to install audio codec. At first, I had audio working on previous versions of OS X (10.12 and earlier) on this hardware, but I misremembered what audio codec and installed ALC898 instead of the ALC892 which is the correct driver for my mobo. I used Pacifist to extract AppleHDA.kext from my unibeast drive and used Kext Beast to install it, and kept a backup. Rebooted, used multibeast to inject ALC892, rebooted, still no audio devices. I then reperformed the same steps, only I used unibeast to reinstall OS X to restore AppleHDA.kext. Still, no output devices found.
