Sorry, here you go.
The dsdt is not the native dsdt. It has been edited for HDMI audio and can be used without additional HDMI audio edits. For ML onboard audio, edit dsdt/HDEF/layout-id to 0x01, 0x00, 0x00, 0x00.

Hello Toleda

I have a doubt, recently i could get the AppleHDA.kext 2.3.1 modified for works on VIA VT2020 chipset audio in conjunction with a patch for the DSDT .. credits to Nithy http://www.osx86.net/downloads.php?do=file&id=3041&page=9

No more VoodooHDA

Is possible active the HDMI audio using your guides?

My rig is

i5 2400
GA-H77M-D3H
nVidia GTX 550ti
Mac OS X 10.8.4
System definition iMac 12,2

Greetings

I do not know if I was wrong to follow the guide but I opened MaciASL and I added the sources github, after I selected first in the patch "UEFI clean compile" and I compiled and after "Desktop-HD4K/HD3K/AMD/Nvidia-A" selecting only because UEFI clean compile gave 2 errors, but when I reboot the boot was very slow and the mouse appeared after several minutes, in verbose mode appears a new string "sound assertion", I attach the 2 files ioreg and unmodified dsdt.

The unmodified dsdt is not useful. Attached the edited dsdt and an IOReg with the dsdt installed. Clean Complies results in 0 errors and 2 warnings. IOReg shows audio is disabled; are you booting with a USB installer?

I have attached the file without modification to see to see the original and ship them to know if the two patches are good for me, mountain lion is installed on my HD with Enoch 2244, I installed Enoch and the only bootloader because I recognize the hd display.
The guide has been carried out correctly?

Nothing attached. Audio is disabled in your system; fix that first.
