you failed to give OS .. To get rid of a sound you can .. Control panel --> Hardware and sound --> change system sounds --> Program events .. highlight sound --> then at bottom of page "sounds" click to open choices on left --> scroll to top and choose none --> click ok That will take away sound event
He did not ask how to get rid of sounds. Windows sound mixer (click your volume icon in bottom right and choose mixer) has separate volume slider for System Sounds so that would cover it.
