Answer #1
It’s simple to know that.
Download this: http://download.fedoraproject.org/pub/fedora/linux/releases/16/Live/i686/Fedora-16-i686-Live-Desktop.iso
Burn it into a CD.
Boot up your PC with CD and then check if sound is working in this other operating system. IF if works then you have a problem with drivers or something. I trully bealive that sound card’s never broke.
You can go to your device manager under Windows and see if some card have a ! in it.

You also need the windows audio service running
net start AudioSrv
The audio troubleshooting wizard should be your first step though
