AppleHDA HDMI Audio [Guide]

Not likely, problem appeared with the first Pascal driver release.

thank you again for that info, based on that have put it in a machine that uses a USB sound solution and not HDMI

Hi,
I have failed to install the HDMI audio driver for GT1030 Nvidia. I have tried the ways listed in your post but still it failed to work.

Note: I had successfully used intel HDMI audio before and I have recently upgrade to GT1030. I am not sure if this is the root ca
use. But I have removed the patches / modification according to your post.

I have attached the required files for your reference. I think I have made some progress, the system can see the nvidia HDMI codec, but not shown in the system preferences, and now i am just waiting for the last piece of the puzzle, I guess


[edited] pls ignore the computer description in the file, actually, My problem is with this machine:..
the correct configuration is i5-4460, Gigabyte GA-B85M-DS3H, with 16G RAM and Gigabyte Nvidia GT1030

Hehehe, thanks toleda, although finally I did not find any boot arg that activates the HDMI Audio... But thanks for all the help anyway, I have learned many new things.

macOS HDMI audio is installed properly and working, Nvidia driver problem.

There is no boot arg for HDMI audio, see Post #1/II. AppleHDA HDMI Audio Methods

Will the AppleALC.kext (1.2.7) work on 10.13.5?

Thanks

I just updated to 10.13.5 and my HDMI audio is dead. I am testing an XFX Radeon Vega 64, just so you know, and it and HDMI audio was working just fine with 10.13.3 and even 10.13.4. I've tried a new AppleALC, tried to build a new SSDT-HDMI.aml, tried reverting to the previous AppleHDA, tried a bunch of things, and it's a no-go.

Audio through the green port on the back of the motherboard does work, but HDMI audio is dead. Booting back into 10.13.4 and the HDMI audio on the Vega works.....

Before I do a bunch of postings on this, do you want to work with me on this? Do you think you can help me with this?

This I cannot explain: I added whatevergreen kext, and initially no change. 10 reboots later, no change. Then, magically, for no reason and no change on my part, not in the bios, and not in the EFI, all of sudden, it started to work....which means I don't need your help......so, thanks, anyway!
