[Easy Guide] ML: UEFI HDMI Audio

[toleda]

Got it working. IGPX was not set to initialize first.

Now I just need to get the SSDT stuff working and I'm golden. I will read that thread. I did notice that I only have 2 P states 15,35. I'm assuming that has something to do with IMac 13,2 being a desktop?

That is why I linked you to the other thread. Chimera 2.2 does not solve the problem you had.

PM is off topic. SpeedStep is not working, turbo is not working.

My DSDT is:
DefinitionBlock ("iASL2lHNkM.aml", "DSDT", 1, "ACRSYS", "ACRPRDCT", 0x00000000)

It's not A.M.I

Determine which framebuffer (01 or 03) gives you a display before you make the edits. Use the corect laptop patches (FB_01 or FB_03) in Post #1. An additional edit may be required in the framebuffer. Reply with the edited dsdt and IOReg.

I patched DSDT with uefi4-hdmi_audio-3-3.txt Laptop LCD black and HDMI TV crappy. HDMI TV is like this : / / / /

Backed to Original DSDT and patched this one uefi3-hdmi_audio-3-1.txt I get Kernel panic.
Now, I'm here with the Orginal one ;-)

No surprise. Read the first sentence of my instructions again. You have to determine what framebuffer works on your laptop before you apply an edited dsdt. Reply when you found the correct framebuffer.

By the way, AppleHDA HDMI audio will not work with Voodoo and the HDAdisabler installed.
