Hi Blitto, Check In System Preferences -> sound -> output is set to internal speakers.
If that isn't the problem Reset PRAM and NVRAM Shut down your Mac Locate the following keys on the keyboard: Command, Option, P, and R. Turn on the computer. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears and before the chime sound. Hold the keys down until the computer restarts and you hear the startup sound for three times. Release the keys.
