What make and model fo keyboard is it?
It's possible that the mute key was pressed during the fall. That could be one of the specific multimedia keys on the keyboard (mine has three separate sound icons, one to lower the volume, one to increase the volume and the mute one has an "X" beside it, across the top above the "F" keys). It could also be a combination of other keys, depending on the keyboard.
