No Audio on ACL892 with 10.8.2 ML

[vaccine]

Hey guys,
I yesterday installed a clean ML 10.8.2 on my PC but get no audio after running Multibeast 5.2.1
The current display(Samsung TV) lists under display, and 6850gpu lists also(but no HDMI audio).

I get no sound out of the internal speakers not do i get anything out of the SPDIF either (ALC892).
Currently under SysPref/Sound, both Output/Input have listings.
There are no HDMI listing for either the GPU or MB(ALC882).
S/L/E has optimised AppleHDA.kext and HDAEnabler1.kext, no ALC8XXX.kext files(clean install)

Not sure where to go from here?

For 892 onboard audio, see ML: MultiBeast - No Audio/Solutions and Problem Reporting.
There is no HDMI audio in OS X until you enable it, see Mountain Lion HDMI Audio

haha.. thought it might have been an easy fix.
should have payed more attention in my compiler class.

so i extracted my DSDT file and there was an entry HDEF, but not much there!
nothing about layout=id etc etc.


so i patched the extracted DSDT file with add_hdef.txt & href_audio_id_1.txt
ran the compiler and get a few errors, 2 errors for patch, HDEF, _ADR?

For dsdt, see [GUIDE] Creating your own DSDT for most boards
for HDEF, see ML: How to Add or Edit dsdt/HDEF

In my case i went crazy with sound on my ML Install.

But somehow i managed to get it to work by installing VoodooHDA 2.7.6 ML.

Now my installtion is cloned to an USB drive (for safety) LOL

Hope it can help
