AppleHDA HDMI Audio [Guide]

[maple4444]

Thanks, toleda.

I thought I just need to 1. install lilu and whatevergreen using multibeast, 2. install AppleALC
The second step is the required in the guideline:

Framebuffer/connector patches

• AMD: Guide How to Patch AMD Framebuffers for High Sierra using Clover
• Nvidia: NVCAP configures all connectors. no macOS support for 2x HDMI
  • AppleALC.kext supports non native Nvidia HDMI audio controllers
• Intel: [Guide] Intel Framebuffer patching using WhateverGreen (max, 2x HDMI/DP/DVI audio)

since I have Nvidia, I use the second item.I thought install appleALC is doing Framebuffer/connector patches.
If that means I need to find NVCAP value then fill it in the configure.list, then I still have trouble to find the NVCAP value. I searched the ioreg couldn't find it.

Update:I found it here. Do I just paste this in the configure.list?

IOReg does not show the kexts installed, that is the first problem to solve

Do I just paste this in the configure.list?

No. As the note says: "NVCAP configures all connectors". Do not touch

IOReg screenshot is useless. Useful, attach IOReg
Install kexts, restart, reply with new files

But I have lilu and whatevergreen in my l/e folder. It just doesn't load. Is it because I used thunderbolt to connect my gpu and monitor? The only way to login macOS with a lg 5k and GTx card is use one display port cable to login macOS with a black screen then plug in the second display port to light up the screen.

I installed them again still not loaded. Can't find it under ioresources.

Full stop, fix it.
No HDMI audio possible until fixed.

HD530 HDMI audio requires working onboard audio. See Post #1/I. Before You Install HDMI Audio/3. AppleALC.kext ...
Onboard audio, off topic

Just thought I'd note that I found the fix. I had saved a downloaded copy of AppleALC and Lilu to my temp folder for Kexts. I downloaded current versions of both, reinstalled them and did a permissions repair and finally I have sound!

my dp ports also have this question...

For a display with both inputs, switch from DP2HDMI or HDMI2DP, same as hot plug.
Video shows hot plug, Nvidia driver problem.

Hello, I am currently using WebDriver 387.10.10.10.40.105
Can I upgrade to WebDriver 387.10.10.40.113 to solve this problem,
Is this a common problem?
thank you

Yes, won't solve problem

Is this a common problem?

All Pascal products effected
Unfortunately, hot plug does not work for some users
