Mountain Lion HDMI Audio - AMI dsdt, Extra/dsdt.aml (1st line)
DefinitionBlock ("./dsdt.aml", "DSDT", 2, "ALASKA", "A M I", 0x00000014)

Introducing a new simple and easy HDMI Audio dsdt editing tool for OS X HDMI audio. Based on MaciASL, the Apply button automatically adds the HDMI audio dsdt edits to your dsdt. This version edits AMI dsdts

Toleda your awesome at what you do, but I'm missing something when going through your guide to get my HDMI audio working.

Everything on my build is working except the audio over hdmi. I have used MultiBeast with the "w/out DSDT-ALC887" and all onboard audio seems to be working fine (with the occasionaly "pop" when an audio blip will play) but I really would like to get the HDMI audio functioning so I can put this build to rest.

So far I have verified the following through IOReg: GFX0@2, MEI device_id 3a1e, and HDEF/layout-id "<77 03 00 00>" I also have DSDT editor. But I must be missing something yet or am getting lost in some process.

Would you be able to simplify a set of instructions or specify a patch for my build with ML, Ivy Bridge, and UEFI (GA-Q77-D2H).

You're the subject matter expert on this and I would greatly appreciate anything you could help me with.
Thanks in advance!

 

[beavjamz89]

I got the "HDMI / Display Port Output" to show up in Audio/Devices, but I don't have the selection in system preferences/sound. Also, my SPIDF option went away, and now I have "Optical digital-out port"

Any help in getting the HDMI/Display Port Output to show up in System Preferences/Sound would be greatly appreciated!

You are not on Voodoo. Optical Digital-Out is SPDIF Toslink out. Attach a copy of IOReg. Guide] How to Make a Copy of IOReg.

Hi toleda, I have attached the IOreg file. The only reason I mentioned the SPDIF/ Digital Optical out note, is because before I did the DSDT edit, my other sound option was listed as "SPIDIF" and not "Digital Optical Out". I didn't know if that would have made any difference in trouble shooting the problem here that the listing changed from SPDIF to the digital optical.

Thanks!

HD4000 HDMI audio is not broken, the Audio_ID is wrong. Set it to 887 for 887 onboard audio and AMD/Nvidia HDMI audio. The Audio_ID is 387 for 887 onboard audio and HD3000/HD4000 HDMI audio.

Edit dsdt/HDEF/layout-id:
from 0x77, 0x03, 0x00, 0x00
to 0x83, 0x01, 0x00, 0x00.
Install dsdt and restart.

Note, when you install the ML_AppleHDA_v2.3.0, the layout-id changes to 0x03, 0x00, 0x00, 0x00.

 

[beavjamz89]

okay, great. I'll give that a try.

hi Toleda,

I have Z77 ds3h and HD3000 (2500k)

Just wandered if you know whether the incompatibility between Z77 and HD3000 will cause any unforseen issues with this guide.

I have succesfully enabled the graphics by changing the MEI device ids in AppleIntelSNBGraphicsFB.kext and AppleIntelFramebufferCapri.kext using this great guide:

www.tonymacx86.com/150-enabling-hd-...therboards-hd-4000-6-series-motherboards.html

Have also enabled 887 Audio using patched AppleHDA v2.3.0 and HDAEnabler1

Have studied your guide and compiled a clean dsdt, the system boots fine.

I then ran Mountain Lion HDMI Audio patch for IVY Bridge and the HD3000 on Z77 patch in dsdteditor

I then deleted HDAEnabler1 and rebuilt cache

Now the system will not boot, I can of course use DSDT=null at chimera to boot with no onboard audio

Where am i going wrong? Have attached clean working dsdt, edited dsdt (not working) and IOreg

cheers Stu

There is a problem. You should not use the 7 series edit kit for HD3000. The reason you can't get to the Desktop is the wrong graphics kexts are loading. Try this:

1. Start with the native dsdt and take it to an error free compile
2. Download the HD3000_AMI_EFI_hdmi_audio_dsdt_editing_kit
3. Apply the patch per the Guide
4. Install the new dsdt
5. Because you have already patched the correct kexts, no dsdt edit is required for MEI at this time
6. Restart.

Reply with the new edited dsdt and a new IOReg.

 

[surfstu]

Thank you for your time...

I have reinstalled HDAEnabler1.kext (is this correct?)

I have used a clean DSDT and applied hdmi_audio_ami_efi_hd3000.txt patch without any edits

Rebooted and saved ioreg

I have attached the new edited dsdt and ioreg

cheers Stu
