Audio - HDMI Audio AppleHDA [Guide]

[xavierds]

Hi guys,

First thanks a lot for all the work, really impressive.

I've been blocked with this for a few days in my new build and I don't really know how to continue.

So It's Asus H97I-Plus (alc887/8 + 3 sound analog output + optical) and the processor it's a Intel 4170T (HD4400). Following the previous tutorials I've been able to make everything work and even the graphic card, now I just need to have the sound over HDMI.

Following the tutorial I've added the sources in MaciASL and I've applied the patch AMI-HD4600-AMD-NVIDIA-A1 without issues but I'm not able to compile. I obtained these errors. What should be the next step ?

Following this If I understand I should also modify the AppleHDA and Azul. I found them in the Extensions Folder but I don't really understand the port assignation from IOJones. Having only my HDMI connected, I get that it's AppleIntelFramebufer@2 with the following information:

AAPL,ig-platform-id, Data, <03 00 22 0d>
Apple Display -> port-number, Number, 0x0

So no port 5, 6 or 7, which patch should I apply ?

PS My bootloader is chimera

Thanks in advance for your time and really nice work

not able to compile.

No way to fix a dsdt with complier error messages. Save dsdt as Format: Disassembled ASL file and attach.
The display is on AppleIntelFramebuufer@2, Port 0x7; use azul-a patch.

Thanks toleda,

I had to re-install the system as I wasn't able to boot it anymore.

Here is my dsdt before to apply the patch.

Thanks for your help View attachment system.zip

PS I had to compress it or it wasn't fitting the files system of the forum.

I had to re-install the system as I wasn't able to boot it anymore.

Installing a text file into a system folder fails every time. Install only compiled binaries. If you remove wrong dsdt file, reinstall is not necessary.
Remove the "I' as the first character in your attached dsdt file.
The guide says apply 2 patches, what patches did you apply?

Hi Toleda,

Started everything from the start,

I've applied the patches: AMI-Clean_Compile-9Series and AMI-HD4600-AMD-Nvidia-A1 and I've one error when doing the compilation:

6/3/15, 7:05:03 PM, iASLByyO7A.dsl(13768) : Error    4057 - Name already exists in scope (_DSM)

Also coming back to the pdf regarding the Step 1:

[COLOR=#1A1A1A][FONT=Verdana]Step 1: HD4600 HDMI Audio kext edits
[/FONT][/COLOR][COLOR=#1A1A1A][FONT=Verdana]1. AppleHDA.kext (select one) [/FONT][/COLOR]

which one should I use in all the list and where I can find it ?

For the Step 2 which is the patching since I'm using version 10.10.3, I don't need to do the step 4 and 5 right ?

Thanks a lot for your help

2nd request; error log is useless, attach dsdt with error.
With the exception of MultiBeast (Downloads - tonymacx86.com), each choice has link.
Correct.

Hi Toleda,

Here is my patched dsdt which I can't compile View attachment DSDT_patched.zip

For step 1 I copy from the multibeast the file AppleHDA-887_v100302.pkg and I've downloaded the file graphics_intel_hd5k-azul-a-90_patch.command

What is the way to patch this file and to replace my actual AppleHda with it ?

Thanks again for all your efforts

See Post #482
Use MultiBeast to install 887 audio
No idea what is the correct azul patch, attach IOReg.

@ toleda hey man,i would like to ask you something.So,all i did to get HDMI audio on my hack was to place SSDT-1 you provide on EFI partition (Clover install)as per instructions (that was way too easy,thanx!).My question is,editing the SSDT-1,can i get dual HDMI audio outputs as i have 2 cards in my build?Currently,only the top card (the one closer to CPU) gets HDMI audio.thank you again.

 

[toleda]

can i get dual HDMI audio outputs as i have 2 cards in my build?

Custom ssdt required. Attach IOReg.
