Without knowing why, my PB has muted its internal speakers' output volume and I cannot figure out how to get the sound back. When I click any of the keyboard keys (F3, F4, F5) which control the sound, all show "muted." When I go to "System Preferences," and select Hardware-Sound, Output Volume shows muted and is greyed-out, so it cannot be changed.

How do I get the muting to stop, please? Thank you.
