This fix is temporary; required until macOS/AppleHDA.kext natively supports 300 Series/Coffee Lake audio.

Supports 10.13.4, 10.13.3, 10.13.2, 10.13.1, 10.13

  1. MultiBeaast TBA

Thanks for verifying the addition I made recently for HDEF 0xa348 in FakePCIID_Intel_HDMI_Audio.kext.

I noticed the unsupported HDEF after receiving a couple of ioreg files from these boards in relation to work on the USBInjectAll.kext github project, and figured that mapping 0xa348 -> 0xa170 might work for those boards, so I just went ahead and added it (and pushed a build) without the ability to test/verify.

So... thanks again!

I've looked a bit but can't seem to find if there is any temporary work around to get the onboard audio working (Z370 series - Coffee Lake) unless I upgrade to High Sierra.

Am I out of luck if I stay at Sierra? I have compatibility issues with software that limit me from upgrading.

which posts are these? I'm really struggling to make any progress, thanks in advance

EDIT: I'm now booted from UniBeast, doing far better. Only problem is, I've got a lot of white noise, which I must get rid of.
