Mountain Lion HDMI Audio

[shipsat]

What have you done to activate HDMI audio? I don't see any dsdt edits. GTX 285 does not support HDMI audio.

After editing my DSDT system not booting. Please help me with editing DSDT for HDMI Audio GTX 670.

You made a mistake; likely missed a step. Attached the edited dsdt.aml.

Specify what steps I need to do editing in the DSDT to activate HDMI on my card GTX 670.
I'm not good in the process, if possible you could help me and edit DSDT? Thanks for help.

What wake messages are in Console/All Messages?

I cannot get to see the messages in console, as soon as I wake my hackintosh from sleep, the screen stays black and I have to hit the reset button for it to work. I had to revert back to using the 898 driver without dsdt and remove the dsdt.aml file to get sleep to work properly.

I've tried redoing all the steps one more time; same result.

Any other guesses?

I have no idea. You did not attach your edited dsdt as requested.

Console/All Messages is a log. Open it and look what happened before the reboot. It will tell when it went to sleep and what woke it up. See what it looks like with your sleep working configuration.

I made ​​an edit DSDT, but HDMI is not activated. I added HDEF, GFX0, HDAU. What did I do wrong?

Need to install the 10.8.2 AppleHDA.kext. Run MultiBeast 5.1.3 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/Witt DSDT/ALC898. This will change the Audio ID to 1 (HDEF/layout-id 1). Verify on board audio.

The PEGP edit are on the wrong device. Restore Device (NPE1) to its native state (i.e., delete the HDMI audio edits). Rename NPE3 to PEGP. Paste GFX0 and HDAU in PEGP. Compile, Install. Restart.


The correct HDMI audio edit looks like this:

6302      Device (NPE1)            {
                Name (_ADR, 0x00010000)  // _ADR: Address
            }

          Device (NPE2)
            {
                Name (_ADR, 0x00010001)  // _ADR: Address
            }

6312      Device (PEGP)
            {
