Fix: Patch the Sandy Lake Audio Controller (0xa170) for Kaby Lake (0xa2fo)
Typo.
I think you meant "Skylake", not "Sandy Lake"...

Weird, AppleALC 1.1.1 works just fine for my motherboard - GA-Z270X-UD3, with the same 100 series clover patches in config.plist, and the audio layout inject on 7 or 11. I've been using it for over a month with no probs.

The only weirdness is the audio system prefs routes the actual "line out" port to the label "internal speakers". Front headphone port works fine! I was hoping to try your new layout id 1 or 2 in v 1.1.2 to see if that fixed it - https://github.com/vit9696/AppleALC/blob/master/Changelog.md

Thank you! I found that new build shortly after reading another post.


Results are about the same with inject layout 1, actual line out port still works fine, still only works if on "Internal Speakers" label in software routing. With layout 2 - "line in" port and "rear" were outputs when switching between the two software entries for "line out", internal speakers didn't work.

Thanks anyhow, I'll still with it and stay on layout 1 / internal speakers (same as v1.1.1 with layout 11) - I use a firewire DAC for my audio monitors, this was for using my stereo receiver & speakers.

Output signal seems to be a bit hotter under "internal speakers" anyway.


EDIT/UPDATE:
I went back to AppleALC v1.1.1 - and layout 11

With that v1.1.2 compile, my front port headphones were crackling something crazy - like when you have a loose or old headphone jack and it shorts out as you wiggle it - that's the sound I was getting, like a series of phase cancellations - rear port was ok.

Patch AppleHDA.kext (use hex editor)
  • Copy System/System/Library/Extensions/AppleHDA.kext to Desktop
  • Edit Desktop/AppleHDA.kext/Contents/Plugins/AppleHDAController.kext/Contents/MacOS
MacOS is a folder. The only file inside is AppleHDAController. Do I edit that?
