Windows 7 and the Realtek ALC850 AC97 chipset

If only it played 5.1 instead of just stereo….

Well you can, after a fashion, get it to play out of all the speakers if you can find your way to the Realtek website and download the drivers.

Of course if you then discover that the port on your motherboard is fried, you have just wasted half an hour of your life.  Aaargh.
