I am currently using Windows Server 2008 RC1 on my workstation (not by choice). Installation went very smoothly, but I can't get sound working. I started Windows Audio Service and installed only available Vista x64 drivers from Intel's site.
The problem is particularly strange because there aren't any warnings in device manager. My speakers/headphones are recognized when I plug them in. Also, there is no audio level detection in the audio mixer's audio level bar; no matter what I play, I can't see the green bar going up. I don't have any knowledge about Windows audio layers, so I can't see where the problem occurred.
The motherboard is D975XBX2 (i975X chipset).
EDIT:
I just noticed that audio is detected in the Control Panel > Sound panel. The bar goes green for the my default device (headphones) just as it should, but still shows nothing for the mixer.

Did you set your newly installed audio device as the 'Default' audio device for windows? Most software uses the windows audio mapper to play sound. If this has no default device, you'll hear no sound.
Go to
Control Panel>Sounds and devices>Audio taband choose your default device for recording and playback.
