Hi guys wondering if I can get some help. Am a little confused on what steps I need to do. Have gone through all the instructions in the front and am confused on exactly what I need to do. I have done a lot and one thing has worked and none others. If someone can just clear up what steps are necessary for my system that will be great.

I have a GA-Z87N-Wifi - i5 4670K, HD4600 Graphics and audio. Just made a fresh install of El Capitan with Clover. This box is a HTPC so technically I only need the HDMI audio port. Mobo has 5 audio ports so its type 1.

I tried the following for HDMI Audio:
1) Multibeast ALC892 driver + optional HD4600 HDMI audio --> Only got Internal speakers/Digital coax audio, no HDMI

2) Added ssdt_hdmi-hd4600+.aml to acpi/patched --> No change; still no HDMI audio. (also tried renaming it to SSDT-1.aml)

3) Tried: ssdt_hdmi-hd4600+_AirPlay.aml in acpi/patched --> System does not start. Reverted back to ssdt_hdmi-hd4600+.aml

4) Downloaded and Ran: audio_cloverALC-110.command; went through the whole patching process --> reboot --> Still no HDMI audio. ACL892 audio still intact.

5) Downloaded config-hdmi_hd4600-100.plist and copied and pasted the info from it to config.plist file of clover folder. (copied everything to the start of the config.plist file) --> Reboot --> HDMI audio now shows up and all other audio options lost. Also system is acting a little goffy, some internal HDs showing as external.

I have done a lot of steps and some work and others do not. I am very confused as to exactly which steps I am suppose to follow. I don't mind reinstalling and starting from scratch, but some help on exactly which of these steps are needed would be great. Thanks!

Ignoring Post #1/Guide always results in failure, see
Table 1: Systems
8. Haswell/HD4600/8series: Guide/HD4600-hdmi_audio

1 and 4 are exactly the same result, one or the other
2 correct
3 disables HDMI audio for AirPay Mirroring
Remove 5/config.plist, see guide for correct config.plist patches
cloverALC ship does enable HDMI audio, patches AppleHDA.kext for HD4600 (necessary, not sufficient)

Hi Toleda,
I am a little bit confused here about the steps to follows for enable HDMI on my build (GA Z87X UD7 TH - i7 4790k - gigabyte GTX 760 2 GB).
I need to enable HDMI audio on both ports ( on board and GPU)
Is it possibile to have a step by step simplified guide for my system ?
Thank you in advance

Hello Toleda,

El Capitan 10.11.2
GTX960
Z97m-D3H



I followed this guide http://www.tonymacx86.com/hdmi-audio/172023-amd-nvidia-hdmi-audio-easy-guide.html


I installed the latest driver on Nvidia website, I downloaded ssdt_hdmi-nvidia-PEG0.zip (as my screen is PEG0 reported by IOREG). I renamed the file into SSDT.aml (as I don't have any SSDT in CLOVER/ACPI/PATCHED) I reboot, it worked perfectly but when I shut down the computer the HDMI audio disappear. So I have to reboot to get it back, but always when I shut down the PC I loose the HDMI audio.


Any help ? :(

Does shut down mean sleep or power down?
No files, no help.

I mean power down.

I figure it out few days ago. I come here to explain how I fixed it, maybe it can help someone.
"Inject Intel" was checked in the config.plist. This is why I lose the HDMI audio everytime I turn off my pc, but when this option is uncheck, the boot become very slow (1 minute, usually it's 25 seconds) It's because I didn't deactivated the Intel HD 4600 in the Bios. So I deactivated, and my PC start working perfectly :)
