daughterhasa2013

Hello: My Daughter recently bought a used 2013 Fusion. She does not have any sound - although the radio turns on, a cd will play, and music from a phone via USB will show it is playing - no sound from any of these - the volume knob shows it should be loud but nothing. She has the factory stereo and we have researched and attempted: reset, unplugging the battery, and have checked all micro fuses related to the radio and speakers. Any other ideas?
