Fixing Audio Problems in Windows 7 x64 on MacBook (Not Pro) and Boot Camp

I was fortunate enough recently to get a license of Windows 7 x64 Home Premium which I promptly installed on my (non-pro) 15″ MacBook.

The install through the OSX Boot Camp wizard went really smoothly and wireless and most other drivers worked out of the box. However, on my early 2008 MacBook, the audio driver did not work (instead only red light constantly came out of the audio jack). Obviously, the driver provided by Boot Camp is not the right one. From my experiences using XP on my Mac, I remembered that the audio card is made by Realtek. After lots of googling, I downloaded the driver directly from Realtek and it worked. Here is the download link. The one I downloaded is Vista Driver (32/64 bits) Driver Version R2.14. Extract the files and run the setup.exe.

BTW, if you are looking for some older versions, you can use this ftp site.
ftp://202.65.194.211/pc/audio/. This is a mirror site used by Realtek. Note that the download speed is kinda slow, so be patient.
