sound not working

My sound on my Dell 3000 desktop hasn't been working for at least 6 months.
The speakers seem to be fine. I get a message that says "Windows Media
Player cannot play the file because there is a problem with your sound
device." I have installed Driver Robot to update all of my drivers. When I
try to install Realtek AC'97 Audio, it says that I need to contact the
hardware vendor that has passed Windows Logo testing. I have no idea who the
vendor is. I've contacted Driver Robot and unfortunately, they don't seem to
be much help.
