which kext for this sound card. is it Azalia or Intel IDT

@The FinnI believe it's STAC9271. There's an installer on the iPC disk, or it should be easy to find a dump to use with HDA patcher.

Thanks Finn!
I will give it a try. I would need to delete the HDAEnabler, AppleHDA & AZaliaAudio before I try this install of STAC9271

By Dump do you mean dump using a linux OS?

nope, STAC9271 drivers don't work.
I don't get the device ids after installing 9271.

 lspci |grep -i audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

@The FinnYes, sorry about that. After more searching it looks like it's actually IDT 92HD71B7. At least that's what I think device id 76B2 is. Try looking here:s http://www.insanelymac.com/forum/index.php?showtopic=13… ↗ Hope that helps

Thanks Finn, you know my system more than I do!
After proper cleanup of old HDA kexts, I installed AppleHDA.kext & HDAEnabler.kext based on thread you suggested.
The actual kexts were extracted from this zip

Speakers /audio controls on keyboard are working without any issues. (Y)
