Windows 7: No sound from builtin speakers

Windows 7/Mac OS X
No sound from builtin speakers

I recently installed windows 7 on my mac book pro. Ever since I installed it, the sound hasn't been working. My mac also has buttons that controls the volume, they aren't working either. I tried using some headphones, I get no sound from them either. I tried updating the drivers, yet windows says that the device is up to date. I checked my speakers on the mac side and they are working just fine. Please help.
