Enabling HDMI audio in OS X Mountain Lion is very similar to Lion. Editing your dsdt has been a significant obstacle to success. Introducing a new simple and easy HDMI Audio dsdt editing tool for OS X HDMI audio. Based on the DSDT Editor built by MaLd0n, pushing the Apply button automatically adds the HDMI audio dsdt edits to your dsdt.


The techniques to enable Mountain Lion HDMI audio are the same as Lion (except HD4000 HDMI audio). The Lion HDMI Audio - Part 1: Requirements guides are current for Mountain Lion. In some circumstances, especially PC and laptop, the Lion guides are appropriate. The Mountain Lion HDMI audio guides are focused on motherboards with AMI or Award (Gigabyte) dsdts. For that reason, there in not an updated Nvidia HDMI guide for Mountain Lion. Instead, guides for AMI and Award Mountain Lion HDMI audio dsdt edits are now available. A minimum set of edits enable AMD and Nvidia and HD3000 or HD4000 HDMI audio in Mountain Lion and Lion. The HDMI audio edits enable HDMI audio automatically for the user's installed and enabled graphics solution

A reality check; even with the correct edits, HDMI audio may not work on your system. This is a do it yourself project, it is rare that someone will offer to edit your dsdt. Occasionally, a user will post their dsdt with working HDMI audio. If your motherboard and BIOS versions are the same as the dsdt posted, you can test that dsdt on your system. Working dsdts also provide validated HDMI audio edit examples that can be applied to your dsdt. If your result is working HDMI audio, you will likely find the process is worth the effort.

Benefits
1. Automated HDMI audio dsdt editing
2. Installs HD3000 or HD4000 integrated graphics HDMI audio dsdt edits
3. Installs AMD/Nvidia discrete graphics card HDMI audio dsdt edits

Before You Start
1. OS X does not provide HDMI audio controls (No volume, no mute, no balance, etc.)
2. The connected HDMI device (TV, receiver, etc.) provides any and all audio controls

Requirements
1. Intel (Note 1)
1a. Ivy Bridge motherboard (7 Series)
1b. Sandy Bridge motherboard (6 series)
1c. Core i3, i5, i7/Nehalem motherboard (5 Series)
2. OS X
2a. Mountain Lion - 10.8 and newer
2b. Lion - 10.7.4 and newer

4. Motherboard onboard audio codec
4a. Realtek supported audio codecs (8xy): 885, 887, 888, 889, 892, 898
4b. Unsupported audio codecs: ML HDMI audio works with any unsupported codec, no onboard audio
5. AppleHDA.kext (one of the following)
5a. ML: Native AppleHDA.kext (unsupported audio codecs)
5b. ML: MultiBeast 5.1.3 or newer/Audio/Realtek ALC8xx/With DSDT/ALC...
5c. Lion: MultiBeast 4.6.1 Drivers & Bootloaders/Kexts & Enablers/Audio/Realtek ALC8xx/Patched AppleHDA/ALC...
6. OS X recognized and enabled graphics with HDMI audio codec
7. Chimera - 1.11 or newer

Special HDMI Audio Considerations
1. AMD/Nvidia/Intel
1a. HDMI audio works with or without onboard audio working
1b. For unknown reasons, some systems do not successfully enable HDMI audio
2. AMD
2a. AMD and Nvidia dsdt edits are the same
2b. HDMI Device_ID and/or Framebuffer edits may be required.
2c. DVI ports do not support HDMI audio
2d. Surround sound (Encoded Digital Audio) does not work with GE=No
3. Nvidia

Hi,

I've been reading this post for the past couple of hours trying to figure out what it means, and while I keep getting a little further, I'm still really confused. I have a Q77M-D2H and there's no DSDT available (that I could find at least). I tried extracting my own DSDT and compiling it so I could save it, but there were errors and so it wouldn't ket me...not sure if this is even the right approach.

This may be a dumb question, but will getting HDMI audio working ever be something that can just be applied through MultiBeast, or will it always require this tweaking? I'm sure with a few more days work (!) I'll be able to get this done, but much of this is so over my head that I find myself wondering if I'm in too deep :)

By the way, thanks for all this information -- not trying to complain, just want to figure it out!

See [GUIDE] Creating your own DSDT for most boards
Unlikely there will be a MultiBeast selection for HDMI audio.

Thanks for pointing me in the right direction toleda -- because it looks like my motherboard isn't on the supported list for the DSDT tool, is it safe to assume I should go the EasyBeast route to generate a DSDT (I get a ton of compile errors in the tool)? I'm guessing that if it messes anything up, I could just delete the DSDT and start fresh? Is is possible that the DSDT generated by EasyBeast would cause issues that I wouldn't notice right away?

Thanks,

F.

EasyBeast does not make a dsdt. Did you use the Fix Errors button in Compile Report of DSDT Editor? If yes, make a screenshot of the errors remaining.

Hi Toleda,

Thanks for the quick response. I did hit the fix errors button -- below is the errors that were remaining, along with the corresponding code:
10484 Error _HID suffix must be all hex digits (GH)
Name (_HID, "ABCDEFGH")


9937 Warning Reserved method must return a value (Integer/String required for _HID)
Method (_HID, 0, NotSerialized)

9937 Warning Not all control paths return a value (_HID)
Method (_HID, 0, NotSerialized)


3135 Warning Result is not used, possible operator timeout will be missed
Acquire (MUT0, 0x0FFF)

2052 Warning ResourceTag larger than Field (Tag: 64 bits, Field: 32 bits)
CreateDWordField (BUF0, \_SB.PCI0._Y0F._LEN, MSLN)

There were also 12 Remark lines, all the same as below (in some cases _T_0 instead of _T_1)

10347 Remark Use of compiler reserved name (_T_1)
Name (_T_1, Zero)



Let me know if that makes sense, and thanks again for your help.

F.

Nothing serious. Go onto the next step, the AMI dsdt editing thread. Download the 7-Series_AMI_EFI_hdmi_audio_dsdt_editing_kit and included is an ami_clean_compile.txt patch file to fix your remaining errors and warnings. Apply the patch and proceed with each step in the guide.

Ok, I patched with the clean compile as you said and got it to compile...one step closer!

Now I'm at the section with the text:
"Edit Open ML_...Series...hdmi_audio_.txt- TextEdit"

I have onboard sound with 6 1/8" jacks, so I'm assuming that falls under 5/6 port on board, and I wouldn't have to change that value because it's already 0x01 -- or is that wrong?

I'm also wondering about the other edits, where it says to find PEG0 and replace with the value from the table. I have a 7 series board, so that means PEGP, right? My question is do I open the file "hdmi_audio_ami_7_series_efi_ivy_bridge" and literally find/replace every instance of PEG0 with PEGP in that text file? When I look at that code, it seems like step 3 is telling me that this code will do that, but maybe I'm missing something.

Also, if I don't care about using the onboard HDMI audio, can I just ignore the GFX0 stuff?

Thanks,

F.

Layout-id 1 is correct. Verify PEG0@1 in IOReg. No changes required for PEG0@1. If IOReg said P0P1@1, then an edit to the patch file are required (find: PEG0 replace: P0P1, PEGP is never edited). Let the patch file do everything. The advantage for leaving the onboard edits is HDMI video is supported (i.e., 3rd monitor) and sound assertions are eliminated.

I'm a little lost here. I see PEG0@1 -> IOPCI2PCI2PCIBridge -> PEGP@0 (see attached screenshot)

I'm not sure what I need to edit in the patch, file, if anything. Just for the hell of it I tried running the patch file without edits, but HDMI didn't appear in sound preferences, so I figured that wasn't the right solution, and I removed the dsdt file and I'm trying again.

Are you able to tell anything from that screen shot?

Thanks again,

F.
