What kind of sound problem? Tell us what is happening?

Do you have the speakers plugged in the right port (light green port)? Have you checked to make sure the speakers are turned on and the volume is up? Have you looked at your Audio/Sound Properties to make sure the volume is up and the sound is not muted? Have you checked the device manager to make sure none of your sound/audio devices have a problem?

If you have a megaphone at the bottom right near the time Doubloe Click on it and make sure nothing is muted and volume is turned up. You can also get to the Audio Sound properties in the Control Panel, click Start/Control Panel and look for Audio/Sound. You can get there by clicking Start/Programs/Accessories/Entertainment/Volume Control.
