I need help so bad!!! Please

I have my hackintosh working almost perfectly internet works and I even have a driver for my ATI 5850. I just cant get my dam sound to work!!! I have a gigabyte x58a-ud3R board that has the realtek 899 on board card.

I have tried to install the driver through multibeast and download the Legacy899HDA key and placed it in the correct folder. Then I ran the keytext utility. That does not work either.

The way I have sound to my computer is SDIF out. I use a optical out to a 5.1 sound system to get sound. (this works perfectly when in the windows side)

I just want this to work so bad.

Please help!!!

Thanks,

Kevin N.
