Need audio drivers for Macbook 2006 (2,1)

Hello! My name is alex, I recently picked up a working 2006 Macbook for 50$ at a yard sale, When i got it i took out the old Hard disk, And put on 256Gig SSD and installed MacOS 10.7.5 Lion, Then i figured I could get more games and better performance on Windows, AND i did not use Bootcamp, I used a partition with windows 7 iso "Extracted" And used "rEFlt boot manager" And Installed Windows 7, Then i realized most of the drivers we're working Except the Audio, I installed driver toolkit, But the driver wont install, Is there a certain driver that someone can provide?

Thanks,

Alex
