Sound Drivers for GA-EP45T-DS3R

Built myself a Hackintosh over Christmas. Installed iDeneb 10.5.5.

Easy install, even got it dual booting with windows. Everything works in OS X except Audio :(

Had a bit of a google search and installed a few kext files for the same chip set and got the hardware to show up in the settings panel, but still no sound.

Has anyone had success at getting the audio to work with this board.

Specs:
Mainboard: Gigabyte GA-EP45T-DS3R (Realtek ALC889A audio chipset)
CPU: Intel Core 2 Q9550 2.83GHz
Video: ASUS 9800GTX

Try with this: ALC889

Look here for prototype_sx post, he explain how to use it
