Check the usual suspects:
Mute switch
Do not disturb feature
Volume buttons
Bluetooth connectivity

Another thing to check, when using the volume buttons, does the screen display "ring volume" or "headphones"? If it displays "headphones" it may think there is something in the headphone jack, which would mute the speakers.
