Could be your headphone jack is malfunctioning.  If the contacts, in the following link, don't return to their resting position, the circuit to the speaker is open circuit.  The diagram on the right hand side, shows the state of the jack when no headphones are inserted; notice the positions of the contacts compared to the left had diagram that has an earphone plug inserted.  Once the earphone plug is removed, the contacts should return to the same position as they originally were in the right handed diagram.
