There is no sound, or it is not loud enough. What should I do?

• Try the following:
  • Press a Volume button on the remote control 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 (PowerLite 1760W/1770W/1775W), set the connected device to PCM output.
  • Make sure any connected audio cables are labelled "No Resistance."
  • If you are using the USB Display function, turn on the Output audio from the projector setting in the Epson USB Display Settings program on your computer.
