Give these a try, you should really go to the MoBo or soundcard manufacturers website but these are the popular ones.

After installing pci soundcard you really should disable the onboard sound through bios as the PC may just have become confused as to which sound its trying to use. Also in control panel under sound devices make sure your soundcard is listed and the mute box is not checked.
