Hackintosh - How to re-enable audio after software update to MacOS X 10.6.8

On my hackintosh I'm using a Gigabyte GA-EP45-UD3LR. I've installed Mac OS X 10.6 with KAKEWALK from a retail Snow Leopard DVD I purchased from our local Apple store.

As I updated from 10.6.7 to 10.6.8 via software update audio functions were totally gone. I used to keep a backup of my AppleHDA.kext, re-installing this kext brings audio function back. I am not using VoodooHDA or legacyHDA. If these are there - delete them.

This method is easy, all you need is kext utility (registration neccessary!)

Step 1: Delete the new AppleHDA.kext that came with the software update (you will find it in your system/library/extensions folder):



you'll need your root password!

Step 2: Open your backup of your old AppleHDA.kext with kext-utility:



...hit "open" and enter your root password!


Step 3: Wait for a moment:



...kext utility just installed your old AppleHDA.kext.

After a reboot your sound should be working again!
