I have updated to 10.6.4, once again the sound breaks.

I kept my legacyhda.kext in the /Extensions/Extra folder and found the updated AppleHDA for 10.6.4.
- I removed the Apple HDA.kext file from the Apple 10.6.4 update (S/L/E)
- Dragged "my" AppleHAD for 10.6.4 over kext utility.
- Ran pfix and disk utility to repair permissions (may not be needed)

Sound is back up and running on 10.6.4

NOTE: Our board has the Audio ID: 889, do not download the other kexts for 887 or 888. I don't believe that they work.

I couldn't attach it because it was too large, please let me know if anyone needs it and I will upload it to megaupload,etc.

Happy Updating...all seems the same with the update
