Audio - HDMI Audio AppleHDA [Guide]

[toleda]

Here you go, this should be everything?
meant delete from this thread or on my machine as well?
My All Messages log is too large

Delete ssdt-1 and ssdt-2 from the machine. Why were they installed?
AppleHDA.kext is damaged and not useable; install native AppleHDA.kext
Clover boot log is missing, attach
To attach large files Finder/File/Compress

Ok, thanks again for the reply.
Looking at how to instal Native AppleHDA a full reinstal from Unibeast (will it kill my Nvidia Drivers?) looks to be the easiest way (at least for me, it's taken weeks to even get close to half understanding one of your HDMI Audio guides, trying to work out another one is going to kill me) and I am beginning to suspect I have made a mess of my instal somewhere along the line... Will let you know where I am once I have a clean instal.
Thanks again.

Had HDMI audio working from a clean Unibeast 10.11 install. Switched Ethernet kexts, suddenly HDMI audio no longer working. Problem stated below in requested format.

1. HDMI device (TV) is not listed as device for sound output in System Preferences.
2. 10.11.3 / GA-Z77-DS3H (rev 1.0) / F9 / i5-3570K / IGFX HD4000
3. Troubleshooted by restoring native AppleHDA, applying cloverALC-110 script (from this guide). (trying for no SSDT solution)
4. IOReg attached.
5. Console log attached.
6. AppleHDA.kext attached.
7. using clover.
8. 1) config.plist attached. 2) clover log attached. 3) none. 4) none.


Thanks in advance for your help.

The ethernet kext had nothing to do with HDMI audio, removing the ssdt was the cause.
Framebuffer is wrong: set AAPL.ig_platform_id to 0166000A.

Sorry, I did not mean to say that I removed an SSDT and then the problem occurred. I meant that I did not want to use a SSDT.

I added your edit to my clover config (under Graphics/ig-platform-id). All that happened was my resolution got screwed up. No change in System Preferences/Audio. Did you mean for me to change this in some other way?

Replaced my AppleHDA.kext, repaired permissions, still no Audio options other than Airport. Do you think this is a sign there is a bigger issue than just the HDMI Audio?
Console, MaciASL, SSDTs, Clover.plist, AppleHDA.kext all included in the zip files, hope thats everything and you are able to help!
edit:forgot the bootlog in the folder so is now attached.

No files attached, no ideas.

Need DPCIManager/Status screenshot.
OS X does not see the audio codec; disabled?
Did you do the clean install? If no, do.

 

[Eightarmedpet]

I'm quite warming to you.
Thanks so much for the constant replies.
I think my instal is a mess so I'll nuke and start from fresh.
Thsnks again.

Hey,

First of all thank you for the guide. It has been very helpful. I used audio_cloverHDMI-110.command to get HDMI audio working on Friday. I've been noticing an unusual problem lately that's affecting HDMI audio. I have no idea if this is at all related to audio_cloverHDMI-110.command, nor am I sure where to ask about this, so I apologize if this isn't the right place.

What's been happening is occasionally when I try to wake my computer from sleep, it will take it a minute or two to start outputting an HDMI signal, and sometimes it never does. My receiver just reports "no signal" and my TV is blank, but I can hear the computer wake up and see the LED lights come on to indicate that it's doing something. A couple times after the display finally came back on, my HDMI audio was gone (the HDMI audio output device was no longer an option in my sound preferences). It only happens sporadically, and restarting always fixes the problem.

Again, I'm not really sure where to ask this. Please let me know if you want me to post all of details listed under Post 1 - Problem Reporting, or if maybe there's a better place to find help on this.
