When you plugged headphones into the audio out jack, did that work ?
There are two 3.5mm jacks on the projector, the "audio-out" one is the lower one by HDMI 2 and the USB. The other one is a trigger for electric screens.
If plugging headphones directly into it doesn't work and the volume is up and mute is off, then I'd say the projector audio out jack is bad and return the projector. If headphones work, then the projector is fine and you should try a different 3.5mm stereo audio cable.
Your other option is to route the HDMI from sources to an AVR that will split out the sound, and then output HDMI to the projector. If your AVR doesn't switch HDMI, then a Monoprice 4x1 switch that separates audio out into toslink and coax is $40.
