Mountain Lion HDMI Audio

[toleda]

Finally, the PEGP is installed on ioreg after putting the DSDT into the hd(0,3). Thank you!!
How can I get my audio back now?

Can't say; screenshot is useless for that question. Attach the IOReg.

Hello. I'm trying to make my HDMI audio to work. It looks like I did all of steps correctly, but my HDMI television just wont appear in settings

Here is the ioreg. Thanks!

Here is the ioreg. Thanks!

No HDEF??? Did you disable audio in the BIOS? What version is S/L/E/AppleHDA.kext? Why did you install S/L/E/HDAEnabler1.kext again.

Yes, I had the on-board audio disabled at that time.
It is enabled now and I just made a new ioreg. Sorry for wasting your time...
My system has the AppleHDA that I got from the 10.8.0. It worked with the 10.8.0.

Thanks

That helped. Thanks. I was mislead by numerous messages that GTX 560 is fully supported in ML

10.8.2 is installed, why 10.8 AppleHDA.kext? Wrong.
Run MultiBeast 5.2.1 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/With DSDT/ALC888 Legacy
HD5770 framebuffer Vervet is no longer loading, how did that break? Fix it.

The original audio kext from the 10.8.2 didn't work. I have tried a few kexts (Including the kext from the Multibeast 5.2.1 as your suggest) and finally got the audio back with the kext from the 10.8.0. That is before having the PEGP and HDAU installed on the ioreg... I thought that I would get the audio back by installing audio kext from the 10.8.0. I will try what you suggest here when I get home from work tonight. BTW, how do I find out if the framebuffer is loading or not? Please advise! Thanks again!

I know I mentioned earlier about sound assertion.. it's just that message is filling up in my console now

11/01/2013 23:56:54.000 kernel: Sound assertion "kTypePinComplex != fType" failed in "/SourceCache/AppleHDA/AppleHDA-179.1.4/AppleHDA/AppleHDAWidget.cpp" at line 1901 goto Exit

Is there a simple way to fix this message?

I don't have solution. The choice is the sound assertion or no HDMI audio.
