Connecting to a Video Source for Sound

You can play sound through the projector's speaker system if your video source has audio output ports. If you are projecting video using the Video, S-Video, or a Computer port, connect the projector to the video source using an optional stereo mini-jack audio cable.
Note: If you connected your video source to the projector using an HDMI cable, the audio signal is transferred with the video signal; you do not need an additional cable for sound.
  1. Connect the audio cable to your video source's audio-out ports.
  2. Connect the other end of the cable to the projector's Audio port that corresponds to the port you are using for video.
