Sound drivers for Win7 on 3-4 year old Macbook Pro

I know this thread belongs in Win7 forum, but I'm posting it here because mac users have experience with these windows sound problems on Macs.

I installed Win7 with boot camp and everything works fine except sound. Windows is telling me that I have my drivers updated, but sound isn't working at all. OS itself is producing the sound (it appears so), but it isn't sending it to my Macbook Pro's speakers. I tried installing quite a few different audio drivers from Intel's website, but none of them fixes the problem. My Macbook Pro is somewhere between 3-4 years old. I don't what is the name of the sound device itself, it doesn't show up neither on Win7 nor on Mac OS X.

Any ideas?

I already did that and none of them works. I can't find audio drivers through their navigation system though (too confusing for me), I only tried those that I found through their search engine.

Can anyone point me to a driver that you used for your macbook pro?

Thanks for the reply! Here is my Hardware Id:

HDAUDIO\FUNC_01&VEN_8384&DEV_7680&SUBSYS_106B1A00&REV_1034
HDAUDIO\FUNC_01&VEN_8384&DEV_7680&SUBSYS_106B1A00

I also noticed one other thing last night. I get red light from audio jack for headphones. I tried turning off the jack with a toothpick, but the light is still there. If I plug in headphones, I get no sound either. The weird thing (and relieving) is that I get no red light when in Mac OS X and sound also works perfectly fine. So it's Win7-only issue.

Tried a few sigmatel drivers, but they don't work. But I did fix it.

The problem was actually that I needed to install Boot Camp on Win7. I feel very stupid now :) 
Well I actually tried that right away from Snow Leopard's DVD, but I didn't find anything windows-based on it, I also didn't know that the drivers I need to install are just combined into Boot Camp for Win.

I always thought of Boot Camp as just an assistant, because I think you can create new partition manually with Disk Utilities, boot from Windows installation DVD, format the new partition to NTFS and continue with installation. But I really had no idea that Apple is also providing drivers through Boot Camp.

Thanks for the help!
