Try this, click Start, Control Panel, Hardware and Sound, and then sound. I there you will see all of your sound devices make sure your speakers(usually the one that says "Speakers High definition audio device) are the default by clicking on the particular speakers your using and click "Set Default". click OK and close out of control panel and see if your audio world comes back.
