Cannot load VoodooHDA for ALC850 on 10.6.6
« on: March 08, 2011, 03:08:32 AM »
My m/b is ASUS A8N SLI, which has an onboard sound card using ALC850 chipset. PCI-E graphic card GeForce 6600 works with NVEnabler+aqua mac fix for 10.6.6.

Win7 Devices driver show that sound card name is Realtek AC'97 Audio, hardware ID VEN_10DE&DEV_0059&SUBSYS_812A1043&REV_A2.

I used the default AppleHDA.kext with class match id patch on 10.6.3 /10.6.4 and it works well (I only need two speakers).
However after upgrading to 10.6.6 sound card is not recognized. 10.6.6 Kexts doesn't have IOPCIClassMatch in the Info.Plist. I thought VoodooHDA was the easiest solution.

So I downloaded and installed VoodooHDA-2.7.2.pkg.zip but still no sound output devices.
I double checked AppleHDA and AppleAC97Audio.kext were moved out of Extentions folder.

I tried modify Info.Plist in the VoodooHDA.kext/Contents, removed IOPCIClassMatch and added IOPCIMatch = 0x005910de and delete Extentions.kext and run Kext Utility 2.0. The system showed panic immediately. After reboot, MAC OSX couldn't be started and CMOS was reset.

Can anyone please advise the way to solve the problem?

Thanks

Couldnt you just use the same 10.6.3 AppleHDA

Have you tried IOPCIPrimaryMatch?

thanks for reply.
yes I tried IOPCIPrimaryMatch, but it still panic.
I downloaded a AppleHDA kext from kext.com but it has no sound output device.
How to get AppleHDA for 10.6.3? Is possible to extract files from installation CD?

You probably could get it from the installation disc or the update. But i'm not gonna be able to help you on that. Don't have a working OS X Installation at the moment and am planning to work on a new project. :)

But try this.
