AppleHDA stopped working for me with 10.6.5 and rolling back didn't help, either. VoodooHDA got my sound back without any screeching that I could tell. Have you tried that?
yeh I tried the VoodooHDA 2.7.2 and all I get is 4 x HDMI inputs and outs. I think it is picking up my GT 240 audio codecs. I tried changing it's info.plist to skip the graphics card codecs but made no difference. I tired other voodoohda's and got no sound at all.
At the moment I can only get sound out the AppleHDA kext in my attachment (as long as I do not sleep).
Thanks for the suggestion.
Can you please attach your voodoohda.kext and configs for me ?
Just need someone who has sleep working and get their audio kext.

also looking for the sleep option fix
See my dsdt.dsl file. There are several changes required to a the DSDT file to enable sleep. Two in particular:
1. making the USB ports appears are "built-in" to MAC OS
2. setting the right value in the SMIP register for the motherboard to goto sleep
Currently, I get the system to sleep (either via "sleep" key on my keyboard, or via Apple menu command or simply via the Power button). The display turns off, usb devices turn off, all fans turn off and the power LED flashes -- just like when I am running Vista.
When I hit the power button (or any key on the keyboard), the display powers up, the fans turn on and the system is back up and running.......EXCEPT the audio. There are audio errors in the kernel log file. It appears something within the audio drivers get corrupted on wake from sleep. I am currently trying to find an audio driver that works after sleep.
Have a look at my DSDT and see if you can make the same changes to your DSDT and compile it. At your own risk
Tip: you can have a test dsdt file that you can select at boot time via Chameleon. Say you have your test file in the root directory (/test.dsdt.aml), then at the Chameleon boot prompt enter :
-v Wait=yes DSDT=/test.dsdt.aml
This will boot in Verbose mode, wait till Chameleon has done it's work and is about to fire-up the Mac OS.
