The attached IOReg does not show working HDMI audio, it shows the first HDMI connector connected to a DP connector in the framebuffer.

To get the first HDMI connector to work:
1. Edit AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri binary

native - 0166000A framebuffer
0A 00 66 01 00 02 03 02 00 00 00 02
00 00 00 01 00 00 00 20 10 07 00 00

What audio devices show in System Preferences/Sound/Outputs and Inputs?

You missed a step
Mountain Lion HDMI audio - Verify S/L/E and org.chameleon.Boot.plist
1. Delete any and all audio enablers (HDAEnabler8??), helpers (ALC8??), etc.; AppleHDA.kext only.

Delete S/L/E/HDAEnabler1.kext, repair permissions and cache and restart. Reply with new IOReg,

OK IT WORKS!!
it was necessary to remove the hdaenabler 1 and my system not work properly with a fresh install of lion Moutaine it works


thank you very much for your work, and your patience

 

[toleda]

OK IT WORKS!!

Enjoy.

The update replaced S/L/E/AppleHDA.kext with the 10.8.2 native AppleHDA.kext. I'll bet you did not backup S/L/E/AppleHDA.kext before you did the update. Your choices are:
1. leave dsdt with current layout-id, run MultBeast 5.0.1/ALC whatever (add motherboard to your profile)
2. edit layout_id to 3, run Mulibeast 5.1.1/ALC whatever, see Mountain Lion: Optimized AppleHDA for Realtek ALC8xx

You're right. I did not perform backup of AppleHDA.kext. I followed your advice and installed ALC892 from MB 5.0.1, yet I used the one Without DSDT. Did not work. I then installed the one With DSDT. No HDMI yet. Did I screw things up by installing Without DSDT first? When you say add motherboard to your profile, yo mean the forum profile right?

Regarding your profile, system says mac mini; edit mac mini to your motherboard. When you selected Without DSDT, S/L/E/HDAEnabler was installed. The enabler interferes with the dsdt. Delete the enabler, repair permissions and cache and restart. Reply with IOReg.
