Sorry for the double post, but I feel obligated to post this.

For anyone having trouble getting the audio to work after the 10.6.3 update, I did find a fully working solution that has all features enabled, including front panel audio, microphone and line-in support.

1) You need the AppleHDA.kext file extracted from the 10.6.2 combo update that can be downloaded from Apple.com's downloads. You also need the LegacyALC883.kext from the ES2L Kit listed in the first post of this thread.

2) Use Pacifist to extract the AppleHDA.kext file from the 106.2 combo update from Apple. When browsing through the update, the file should be located in System/Library/Extensions.

3) Replace AppleHDA.kext in S/L/E on your own Hackintosh drive with this older version. Open Disk Utility and repair your permissions.

4) Put LegacyALC883.kext in your /Extras/Extensions folder (located in the root of your Hackintosh drive.) Use the pfix utility to repair the permissions on drive.

5) Restart and you should be golden.

**Be aware that I'm no expert on this. I'm guessing you'll also need a patched dsdt.aml file that's outline in the first post of this thread. I also doubt this fix will work with other models/brands of motherboards.)
