Do try Jeff's suggestion, it is probably that the background sounds (mainly the prime mover/motor) have been turned down. If you hear bell, horn and dialog, the railounds hardware, loudspeaker and physical volume control are all working correctly. No motor almost certainly means the background sounds have been turned down all the way.

Worked for me. Good Luck!
