If the charger is o.k. then your battery won't hold a charge and needs to be replaced.

First thing to check is your settings for sound. Go into settings and click on sound . The options are there. Make sure it's not on mute or something similar. Try changing the setting. Next is plug in your earphones in the jack. If that works then your jack is open after you take the jack out. If none of this works then a connection to your internal speaker has come loose or off.
