Mountain Lion HDMI Audio - AMI DSDT

[toleda]

Yeah my Card is on second slot PciEx16_2 on my motherboard (Not first big blue slot, not the second PCIE small slot but the next big one - identified as PciEx16_2.) Is this changes things? Also could you please confirm the names of the device PEG7@7 is the correct one.

What version of S/L/E/AppleHDA.kext is installed?
PEX7 is correct if you leave your graphics card where it is.
Don't patch yet.

Hello there,

Version of AppleHDA.kext - 2.3.7-toledaALC888leg.

dsdt/HDEF is not correct; the patch will fix it. Delete S/L/E/HDAEnabler1.kext
Use the attached patch file: MaciASL/Patch/Open/Downloads/p6tse-hdmi_audio_ami_5_series_amd-nvidia-1/Apply etc.
Follow the remaining steps in the guide.

560 HDMI audio is not supported natively in ML. Edit AppleHDA.kext as described:

AppleHDAController binary
find: de 10 ea 0b
replace: de 10 0c 0e (2x)

Hello,

Unfortunately, this wasn't successful.
AppleHDAController Binary edited. Applied the patch with PEX@7, tried also with PEG7@7 but with no luck. HDAEnabler1 deleted. I have checked every time the system config and no new device was added. I can see that when I apply the patch I have additional entry in Intel High Definition Audio named Audio / Display port but didnt have output device in the Audio properties (no new device).

Think that I'm one of these that mystically can't start it

Long live and prosper man

Hello,
Unfortunately, this wasn't successful.

My mistake. Go back to the dsdt attached earlier. Manually delete Devices GFX1, GFX3 and GFX7.

Device (GFX1)
                {
                    Name (_ADR, Zero)  // _ADR: Address
                }

Apply the v1 patch attached. Reply with a the newly edited dsdt and new IOReg.

Hi, Thanks for your easy guide.

I have Gigabyte EP45T-USB3 board and Nvidia GTX760 graphic card.

Too old and Too new.


I didn't make it with my own try.

Plz plz.. edit my dsdt to enable hdmi audio.

 

[toleda]

I didn't make it with my own try.

3 problems:
1. Delete S/L/E/HDAEnabler1.kext
2. You applied the edits twice and the result is trash. Fresh dsdt, apply the edit once.
3. PEGP address is wrong, edit
Name (_ADR, 0x00030000)
to
Name (_ADR, 0x00010000)

Reply with IOReg and edited dsdt.

Thanks for help,

I think I uploaded dsdt without patch applied.

Whenever I tried patch, there was device(IGPU), not (GFX0).

Is this right?

My chipset is p45 and there is no internal graphic.

I used 5 series patch.
