serious
Have you looked at the SOUND / AUDIO Forum - this is more up their alley
Also as you made a DSDT w DSDTSE the audio info that is in the DSDT may need tweaking ( this is normal for non standard codex)
Also you could see this link -

DID you use the link that TonyMac has for making your own DSDT file - involves a off site webpage and you may need to patch the DSDT file made w this method w an unique Audio patch for the DSDT.

I tried numerous solutions and codecs available. Including the Azalia Audio link you provided. I also patched my DSDT with the Hi-Def section included with the supposed Xml and Pin configurations and no luck whatsoever. The furthest I have gotten is having my sys profile recognizing intel hi-def but no audio inputs or outputs recognized. Is there any hope of a preconfigured HDA kext or ALC662 kext in Multibeast. There are actually quite a few of us out there who would be so gracious for such a wonderful gift. LOL . Here is the stock specs for my system. The only thing different is my Asus 8400 GS 512MB Silent Video card. Thanks for your reply. P.S I'm running ML 10.8.3. thanks again.
