AppleHDA HDMI Audio [Guide]

[toleda]

upgrade did not break HDMI audio

Not correct, AppleALC.kext has a fix as noted in Post #2.

 

[toleda]

If u want this is the 10.13.4 file

AppleHDA/10.13.4, breaks Nvidia HDMI audio
AppleHDA/10.13.3 and previous, working Nvidia HDMI audio

@toleda there is something wrong with SKL framebuffer patch. Normally I am using AppleALC.kext for sound. But I want to try this audio_cloverHDMI-130_v0.8.command. First I removed AppleALC.kext then start command patch. My system has just Intel HD530 graphics I choose just that options say no to AMD/Nvidia and as you say removed HDAS-HDEF from my ACPI/patch from config.plist and restart. But my sound is gone and every boot I starting to get the signal loss this loss just for a second. But I can boot. When I remove SKL framebuffer patch signal loss gone. Do I want to ask you this why is this signal loss happening?

I forgot this I am using IntelGraphicsFixup.kext should I remove this and use inject Intel and ig-platform-id?

But my sound is gone

Expected, sound will not return until cloverHDMI runs and installs the ssdts

Which ssdts are you mention? Hdas-hdef and 530HDMI? I already run this command audio_cloverHDMI-130_v0.8.command two ssdts already installed but no sound and extra signal loss came.

I lost sound of Display Port from installation of 10.13.4

Get my sound back by Workaround 1 in Post #2.

Nvidia HDMI Audio/10.13.4
Workarounds (select one):

1. Backup 10.13.3/AppleHDA.kext_v280.12 prior 10 10.13.4 Update, install with kext installer to 10.13.4

If any of you need AppleHDA.kext_v280.12 (extracted from OS 10.13.3), see attachment.

My steps are:
1. After installation of OS 10.13.4, install [AppleHDA.kext_v280.12], restart
2. Install [Realtek ALC1150] and [100 / 200 / 300 Series Audio Support] by MultiBeast (Version 10.2.0), restart
3. Try plug in cable to different Display Ports on the graphic card, one of them worked for me.
