Connection
When connecting a signal source to the projector, be sure to:

described below:

Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your 
presentations, and also connect separate amplified speakers to the AUDIO 
OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the 
audio output of your Video source device to that sound system, instead of to 
the mono audio projector.
Once connected, the audio can be controlled by the projector On-Screen 
Display (OSD) menus.
