Mountain Lion HDMI Audio

[andeify]

No onboard audio; for HDMI audio only, install the native ML AppleHDA.kext.

When I do, there are no Output devices in System Preferences.

Edit dsdt/HDEF

Changed, Rebooted. Still no Output devices.

Do I need the device HDEF if im not using onboard audio? Can I remove it altogether?

EDIT> Just noticed this thread. It seems this card may require AppleHDAController to be edited for it to work.

HexEdit/AppleHDA.kext/Contents/Plugins/AppleHDAController.kext/Contents/MacOS/AppleHDAController binary
Find: de 10 ea 0b
Replace: de 10 08 0e (2x)

Can Injectors do this? Can this not be done from E/E?

What display is attached? What version is AppleHDA.kext?

Its hooked up through a Pioneer VSX-321 AV receiver to a Samsung smart TV, Audio Midi Setup shows "Samsung".

AppleHDA is 2.3.7 - native. (OS is 10.8.3)

MIDI and System Preferences/Sound/Output should say Pioneer; strange. Regarding HDMI audio, I do not know why it is not working with the native AppleHDA.kext. Use MultiBeast AppleHDA if it is working.
