Just Lost sound on iMac

[Walkaa]

Hi guys i'm new to to mac so i may be being stupid but i was playing around iTunes open and everything then suddenly no sound, it was fine before so i checked all my setting everything's fine, checked wiring and power to soundsticks all good. Reboot and the loading alert plays nice and loud as always but log in and still no sound. Any clues?

Move the slider you mentioned just in case is the only thing i can say. As my mac mini is on its way.
