Here is a screen shot of what is under Sound, Video, and Game Controllers: http://i.imgur.com/Ru4bj.png
I have tried installing Realtek drivers but the install doesn't work or something of that nature.
Basically when I try to install it, it says I did, then asks for reboot.
So I reboot, and it automatically installs what is in that screenshot.
Realtek is no where to be seen on my computer.
