There is no sound. What should I do?

• Try the following solutions:
  • Press a Volume button on the remote control or projector control panel to adjust the volume.
  • Press the A/V Mute button to resume video and audio if they were temporarily stopped.
  • Press the Source Search button to switch to the correct input source, if necessary.
  • Check your computer or video source to make sure the volume is turned up.
  • Check the audio cable connections between the projector and your video source.
  • If you do not hear sound from an HDMI source, set the connected device to PCM output.
  • Make sure any connected audio cables are labelled No Resistance.
