I accidentally deleted something and now I have no audio output.

I tried to get files AVI on a D V D - R.  I deleted a program that says it has not been used for several years.  The window in the control panel says no device.  It comes to my work computer, are some of my students to read the reviews.  I need to hear noises on this computer.

Even the icon to turn off the sound upwards or downwards or to remain silent is not on the Board.
