AppleHDA HDMI Audio [Guide]

Output attached.

See Post #1/IV. Problem Reporting; attach all requested files

Without shutting down the PC or anything, unplug iGPU, plug into nVidia: audio works.

Exact nature of the problem. Driver does not detect HDMI audio device on boot and does detect HDMI audio device on hot plug. Clearly, a macOS/Nvidia/Pascal bug.

AppleHDA uses HDEF
Asus Prime Z270K uses HDAS.
Install ssdt_hdef-1-100-hdas.zip, restart
Run cloverHDMI, restart

Did the above procedure, now it detects my monitor but yet no sound, plus everything that has audio included won't play as opposed as simply doesn't output sound: Youtube videos would not start etc. Here's the files. Thank you a lot, Toleda!

PS: MacIASL still doesn't even open its main window but I was able to export the needed file anyway.

1. Description of HDMI audio problem
   • After following the guide, no audio from nVidia HDMI or Intel HDMI ports. Workaround is to boot with the cable connected to the Intel HDMI port and change to the nVidia HDMI port.

   • macOS 10.13.2/H97I-PLUS/2704 (latest)/Intel i5 4690K/EVGA nVidia GTX 1080 SC
3. Procedure/Guide used

My understanding is, if this is a bug I have to live with it until they decide to fix it, correct? Also, I haven't tried with a different cable to discard that's the issue, but audio works correctly from my windows partition.

yet no sound

no audio from nVidia HDMI or Intel HDMI ports

IOReg shows Nvidia HDMI audio working and Intel graphics is disabled.

Yes.

audio works correctly from my windows partition.

Are you saying macOS/Nvidia HDMI audio should work because Windows/macOS/Nvidia HDMI audio works?

I'm saying we can discard a defective cable/port/etc. if the same hardware is working with different software

EDIT: Is there a software command to fake the hotplug or the like? Is really annoying having to disconnect and connect

Is there a software command to fake the hotplug or the like?

No. A DP2HDMI adapter is a better band aid.

Hi there,
Using an Intel NUC 5i7RYH as Hackintosh and all is going fine so far. But I can't get your script to run properly.
Here's a quick breakdown of the problem and (I hope all) necessary files attached.
