Look in device manager..





You might need to be logged on as an administrator in order to do this.





Open Device Manager, click Start, and then click Control Panel. Double-click System. On the Hardware tab, click Device Manager.





See if there's a warning triangle next to your sound driver. If that's the case, try rolling back/updating the driver. If that fails or you don't have one to roll back - look on the manufacturer's site for the correct drivers for your OS/sound card, or use one of these generic ones.
