One way....probably the hard way...is to go into Control Panel and click on Hardware & Sound. (Win7...it may be called something different in XP or 8.

On some puters...mine...there is a speaker icon on whatever that bar is called across the bottom of the monitor screen.

Edit: HA! MAC beat me. But if you don't see the speaker icon go into Control Panel.
