My audio is still playing when another image source is selected. What should I do?

• Because there is only one audio port on the projector, your computer and video devices must share it to play sound. When switching between image sources, be sure to connect the audio cable to the computer or video device you are projecting from. See Connecting to a Computer for Sound or Connecting to a Video Source for Sound.
  
  Note:
  If you connect using an HDMI cable (PowerLite 1760W/1770W/1775W only) or use the USB Display function, the video and sound are both transferred and you won't need to connect any additional cables for audio.
