You
can play sound through the projector's speaker system if your video
source has audio output ports. Connect the projector to the
video source using a stereo mini-jack adapter cable (with one 3.5
mm mini-plug and two RCA plugs).
Note: You can also
use an RCA cable connected to the audio adapter cable that came
with your projector.
Connect the audio cable to your video source's audio-out
ports.
Connect the other end of the cable to the projector's
Audio port or ports.
