You haven't given any brand name and model number of your device here. Yet, all audio equipments this fault will be the same. Either the Audio Ouput IC of your device or its Speaker is faulty. As far as earphone socket is working, the speker of your device has damaged. If output IC has damaged, there will be no sound with earphone socket. Check the speaker of your device. The voice coil in the speaker is damged. You can check it without any multimeter, Just take a torch cell [new one], connect its two terminals with two piceces of wires, and touch intermittantly at the two speaker connection terminals. If the speaker is good, you can hear a "Dup" sound for each touch. If not, it is faulty, and should be replaced with an identical one. Here, the spaker must be faulty. You have to open your set to chek it. OK.
