Never turn the audio off!

HELP!!!!!!
A month or so ago I muted my speakers on the taskbaar icon and have not been able to turn them back on since. By now I figure I have the entire computer out of sync trying to fix the problem myself. Oh, did I forget to mention that I am almost computer illerate, but I'm trying to learn.
I will appreciate any help. Pride prevents me from connecting with a paid Teckie.
