AppleHDA HDMI Audio [Guide]

Cannot replicate the error. Attach is the script edited config.plist. Copy
config.plist/KernelAndKextPatches/KextsToPatch/Item 0 to your config.plist.
Install, restart, reply with new files.

Well, partial success... After installing config.plist/KernelAndKextPatches/KextsToPatch/Item 0 to my config.plist (the file is attached) and reboot the Samsung HDMI device appears in Sound-output.
But can't hear any sound playing a video or music!
So I've ran your script again against the installed config.plist. The first entry got removed after the script ran, and the script shows the same error. (The resulting config.plist is packed in CLOVER.zip).
I'm also attaching other outputs, all of these are after rebooting with your item in KextsToPatch installed.

To confirm, the script does add and suggest a GFX0 to IGPU patch right? I already had one on there when I ran the command (Which fixed dual display for me btw, so thanks), which is why I am asking. Also, should I keep intelgraphicsfixup?

Well, partial success.

HDMI audio working

can't hear any sound playing a video or music!

User error, see Post #1/I. Before You Install HDMI Audio/3 and 4

ran your script again against the installed config.plist.

Broke HDMI audio, why??

script shows the same error.

Expected, the script issue is caused by your system; no idea why.

after rebooting with your item in KextsToPatch installed.

Working HDMI audio, no further action required.

Yes. Clover patch disables audio ssdt.

should I keep intelgraphicsfixup?

What does it fix for your system?

 

[Pintglass]

No idea. What does NividiaGraphicsFixup.kext do for your system?
Clearly NividiaGraphicsFixup.kext does not enable working HDMI audio, post the developer for clarification.
An experiment; remove NividiaGraphicsFixup.kext, restart, reply with new files.

I've removed lilu.kext and NividiaGraphicsFixup.kext
when running your script after removing them it installs SSDT-HDMI-NVIDIA-PEG0.aml in efi/clover/acpi/patched

I've already seen that, so changed from hdmi cable to a displayport to hdmi cable but still no audio

Attach IOReg for each DP port.

Hi,

1. I am currently not getting Audio on HDMI. I am able to get sound via motherboard port as well as the frontend headphone port.
2. OS X Version 10.13.1, MB: GA-Z270-HD3, BIOS version F7, CPU: I5-7500K, Graphics: IGPU 630
3. AppleALC. Fixed HDEF, Picked Layout ID:1 (as you suggested on an earlier thread), placed (most recent versions of) AppleALC.kext and Lilu.kext in EFI/Clover/Kext/10.13
4. Copy of IOReg attached.
5. diskutil ouput Attached.
6. AppleHDA.kext attached.
7. Screenshots attached. Do not see Intel High Definition Audio (may be the problem)…
8. No Script used. Also tried disabling HDAS to HDEF and running the script provided in https://www.tonymacx86.com/threads/applehda-hdmi-audio-guide.234735/ Did not work so reverted back.
9. No SSDT patched. DSDT attached.does this m
10. Done.

Two questions.
1. Does disabling HDAS to HDEP patch, break the sound on the audio port?
2. I have two screens I switch between. TV and Monitor. Use same HDMI cable. Does this method support two devices?

Please help. Thanks.

Attach IOReg for each DP port.

I've only got one displayport on the card of which i have attached IOreg with my other files in the previous post
