unable to resolve using method 2 (AppleHDAController patch which I think I did incorrectly).

config.plist: no AppleHDAController patch
Try again.

Try again.

Re-read post #2 and the link to FredWst and success! I now have HDMI audio.

Thanks for all your help and patience on this thread.

Hi Toleda,can't figure out why I must reconnect DP/HDMI Cable at every boot for Audio recognition even if from IOReg I can see Injection working.
If I use verbose mode I can see Audio Injection but even if I connect and reconnect DP/HDMI Cable Audio will not work anymore.

I am actually using a Z370-F (S1220A) and an NVIDIA GTX 1070 injected with AppleALC (1.2.6) , Lilu (1.2.3), NvidiaGraphicsFixup (1.2.5) and Sleep/Wake CodecCommander.
Webdriver: 387.10.10.10.30.103 injected with Native NVRAM( no InjectWeb/nvda_drv=1 flag in Config.plist ) from Vulgo Post.

Attached Requested Files in Problem Reporting.
Many thanks in advance for your help & support to the community.

Problem report:

1. No HDMI audio option in Sound Settings.
2. 10.13.4/Gigabyte GA-Z170XP-SLI/BIOS f21/CPU 6700k/Dual Nvidia 1080Ti
3. Ran the command then Patched KextsToPatch as well as I could given instructions

4. - 11. See attached. I didn't include DPCIManager because Avast flagged it as malware, but I included everything else. I had no ssdt.aml, but I included the other aml files in the patched directory (lowercase p).

Hi Toleda,

Just got the hdmi audio working on my gtx960 by following post 2. But I noticed the screenshots in those instructions showed device-id as b90f, but the kextpatch would replace with 0fb9.
In my case, I got it working by *not* reversing those numbers. I dunno why it's different. Maybe this will help anyone with the same issue.

Anyways, thanks for the help!

You are correct, my mistake. Post #2 updated. Thanks

Trying to get hdmi audio working on my gtx950 by following post 2.
THis is my ASROCK Z280 Gaming-ITX/ac MB build. Just updated from a working 10.13.3 to 10.13.4.

I have a novice question. How do I 'compile' AppleALC as in post 2.

My %B - build attempt just fails after downloading the AppleALC-Master, opening it in XCode 9.3 and attempting a build.

Attempt to build

The build fails with a missing file error, but this second screen shot shows that I have put Lilu.kext in the expected location.
Don't even know why it is looking for that kext while attempting build of AppleALC...

Existence of missing file

I must be doing something stupid as usual. Advice sought....
