As I needed to used the PCIex1 slot for my BCM94342 network card, I had to move my GFX950 from the x16 PEG0 slot to this PEG1 x8 slot.

All Line In/Out and HDMI devices available.

Yes I had my HDMI audio working- but now it is gone. I realize I may have to change some of the Clover Kernel patches but I can't figure out which. Can you help / suggest what needs to change?

no audio on the display using HDMI
cloverHDMI does not install anything when HDMI audio is already enabled
Installed every method, expect failure.
Remove HDMIAudio.kext
WhateverGreen is installed, is it required?
Restart, reply with new files

Got it. I will try to uninstall HDMIAudio and Whatevergreen. Than I will try the script. Let's see... If that does not work I will generate new debug files. I will keep you all updated.

I tried method one....clover install and ran the audio_cloverHDMI-130_v0.8 patch and got the following error:

HDMI audio codec(s)
Intel: 0x8086280b
Device ID: 0x16590000 not supported
rm: /tmp/HDEF.txt: No such file or directory

So, troubleshoot that or move on to method 2?

I also have a Realtek ALC3234 (ALC255) with vendor id 0x10ec0255 that works using the laying id 3 with the vanilla method.. just don't want to do anything that'd break that.

I have tried cloverHDMI report for a NUC DC53427HYE and El Capitan.

Here is IORegistryExplorer and config.plist for clover. In my /EFI/ACPI/patched I have:
SSDT-HDEF-3.aml
SSDT-HDMI-HD4000.aml

The device is showing up in the system report, but no device is available as output in preferences. What am I doing wrong?

Thanks!
