Hi,

I recently installed Windows 7 Ultimate 32Bit (build 7600) with SP1 (all updates) on my MacBook (not sure which, its Intel 1.8Ghz).

I installed BootCamp, and I've upgraded it to 3.1.

Everything seems to work except the audio device.

I've Googled, and tried:
installing in safemode
downloading various versions of the realtek driver package (but the driver exe in program files won't even open)
installing in compatibility mode
Using the standard High Definition drivers

Under playback devices it says "No audio devices are installed"... and when I click the speaker button (with a red X on it) it takes me to trouble shooting....

Can anyone help me out? Cheers
