Ok, since so many seem to be having problems getting sound working with the ALC885 and ALC889A codecs, here are some easy to follow step by step instructions:
One pre-requirement for this to work on Gigabyte motherboards is that you install the latest BIOS. I don't know if this work on motherboards by other manufacturers. It also requires that you've updated OSX to 10.6.2 and have the right DSDT.aml file installed.
1. Go here
2. If you haven't registered, register with the site
3. Download the "Series of LegacyHDA.zip" for the ALC888, the "Gigabyte_ALC888b_P55.zip" for the ACL888B and the "Gigabyte_ALC889_P55.zip" for the ALC889 toy have to go to this post and download the file at the end of it (requires registration)
4. Extract the zip file
5. Open the folder into which the files unziped
6. Ok, this is the tricky part, as you now have to chose one of the four folders depending on the configuration of your onboard audio solution.
6.1. Have a look at the rear of your system, if you have five 3.5mm audio jacks, then you use the 3outs2ins files and if you have six 3.5mm audio jacks, then you use the 4outs2ins files.
6.2. The check if you have connected up the front audio jacks on your case (if it has those) and which type of connection you've used. There are two types, AC'97 and HDA, they're generally labeled on the connectors that attaches to a small green connector on the motherboard. Use the Legacy file if you have an older case and you've used the connector labelled AC'97 (or none at all) or use the HDA if you've used the HDA connector.
7. Copy the LegacyHDA.kext to the Extra/Extensions folder.
8. Drop the Extensions folder onto the Kext Utility (it's part of the MultiBeast) and wait for it to finish.
9. Open the utilities folder, start the disk utility and repair the disk permissions.
10. Reboot
11. If you've followed these instructions to the T then you should have sound by now
If you're not using an edited DSDT with the right audio settings for your motherboard, then follow these steps to get sound working
1. Go back to the ALC889a_LayoutID_885 folder
2. Open the HDAEnabler_for Snow folder
3. Open the HDAEnabler_885 folder
4. Use kexthelper b7 to install HDAEnabler.kext
5. Open the utilities folder, start the disk utility and repair the disk permissions.
6. Reboot and it should work
Please note: Do NOT install the Mac Pro audio update, it will break the sound. The only fix for this is to re-install the AppleHDA.kext
