You may have accidentally pushed the mute button on your computer. Fortunately, the situation is easily reversible. On most Macs, PCs and laptops, there will be a number of ways you can put the sound back up to its original level.
On the toolbar along the bottom of the screen of most PCs or laptops, there will sometimes be a symbol like a megaphone. If you click on that, a thermometer type box will appear. There will be a slider on the box and if you move that up and down you can adjust the sound and return it to its original level. On Macs, this megaphone symbol is generally situated at the top of the screen. You will then follow the same instructions as above.
On the keyboard for a desktop Mac (i.e. One with a separate keyboard and monitor), there is usually three megaphone symbols above the number grid. The symbol with a single racket reduced the sound level, the symbol with several brackets of increasing size increases the sound level and the symbol with no bracket mutes your computer. If you have accidentally pressed this last one, pressing it again will restore the sound.
On many laptops, there are a similar trio of buttons, one for muting the sound, one for lowering the sound and one for raising it.
Most computers are fairly different so you may have to look around for a while, either looking for the keyboard key or the on-screen icon to restore the sound. In most cases, the loss of sound will have been caused by accidentally pressing a button on the keyboard or screen, so there is nothing to worry about. However, if you try restoring the sound and it remains silent, you probably should take your computer to a computer shop.
