I m Using win XP, Having sound problem plz help.

Hi, i want to put Volume Control on the task bar of my system's desktop. But when i go to control pannel and open "sound and audio devices" no audio devices is written over there and all options related to VOLUME are fuse. So i can not use the option to "place volume icom in the task bar " WHAT IS THE PROBLEM AND WHAT SHOULD I DO. My media player is producing sound and working ok. Thanks in [email protected]
