R9 270X and HDMI Audio

[n1con]

Hey Guys,

im up and running here on my 10.9 Mavericks Hackintosh. Everything is working except HDMI Audio on my R9 270x. I downloaded Vlada's R9 270 installer and my graphics card is recognized as a R9 2xx Series in the system informations. I'm a bit of a noob when it comes to kext edit's and stuff. I installed using the DSDT-free method with Multibeast. Hope someone can help me out here.

Thanks in advance

AMD HDMI audio requires a lot of work. See Mavericks: HDMI Audio - AppleHDA

Thanks for your reply. I saw the guide on customizing the AppleHDA, but which guide should i use? Is the HD7000 guide working for R9 2xx as well?

Post #1 of the thread linked above: Requirements/2. Graphics/2. AMD HD5xxx/HD6xxx/HD7xxx/R7/R9. The technique is the same for all AMD graphic cards with an HDMI audio codec. AMD7000Controller.kext supports specific HD7xxx/R7/R9 graphics cards.

If i'm not mistaken i would need a DSDT for those edits. But i chose the DSDT-Free method with MultiBeast. Do i have to do it all over again or can i generate a dsdt file for my hackintosh?

No such thing as dsdt free on Intel computers; its part of the BIOS. Extract with MaciASL.

Alright so i extracted my DSDT with DSDTSE and i am currently doing the DSDT Edits. I'm a little bit confused where those edits really belong. In the tutorial it says:

With GraphicsEnabler=No in org.chameleon.Boot.plist, make the following changes to your dsdt.

Add the following code to Device (GFX0) - Modify for your particular Radeon HD 5xxx or HD 6xxx graphics card.

Code:
Store (Package (0x0C)
{
"@0,name",
Buffer (0x0D)
{
"ATY,Uakari"
},

"@1,name",
Buffer (0x0D)
{
"ATY,Uakari"
},

"@2,name",
Buffer (0x0D)
{
"ATY,Uakari"
},

"@3,name",
Buffer (0x0D)
{
"ATY,Uakari"
},

"model",
Buffer (0x13)
{
"AMD Radeon HD 5870"
},
}

I'm not really sure where to put these. It looks like they were meant to be put in a method. Device (GFX0) is full of Methods but which one is the right one?

My 2nd Question would be the edits made to Device (PEGP) do i copy all three devices in the one device? The brackets suggest it but i'm not really sure.

Thanks for your help

Graphics card edits are added after the HDMI audio is enabled in OS X. See Post #2.
BTW, in your unedited dsdt, GFX0 represents integrated graphics, not discrete graphics.

I'm not really sure what you mean with "after HDMI Audio is enabled". Does this mean i should just do the Kext Edits now? Because i tried that but i can't find HDAU in IOReg so i figured i will have to do some editing in the DSDT right?

Enable Mavericks HDMI audio. Again, use the guide linked above.
