There is no sound. What should I do?

• If there is no sound when you expect it or the volume is too low or high, try the following solutions:

  • You must connect external speakers to the projector to hear sound.
  • Adjust the projector's volume settings.
  • Press the Shutter button on the control panel or remote control to resume video and audio if they were temporarily stopped.
  • Check your computer or video source to make sure the volume is turned up and the audio output is set for the correct source.
  • Check the cable connection between the projector and your video source.
  • Check the audio cable connections between the projector and your video source.
  • If you do not hear sound from an HDMI source, set Sound Output Format to PCM in the Sound menu.
  • Make sure any connected audio cables are labeled "No Resistance."
  • If you are using a Mac and you do not hear sound from an HDMI source, make sure your Mac supports audio through the HDMI port. If not, you need to connect an audio cable.
  • If you want to use a connected audio source when the projector is off, set the Standby Mode option to Communication On and make sure the A/V Settings options are set correctly.
  • If you want to use a connected audio source when the projector is off, set the Quick Startup option to Off and make sure the A/V Settings options are set correctly.
  • If the volume for the computer is set to the minimum while the projector's volume is set to maximum, the sound level may be mixed. Turn up the computer's volume and decrease the projector's volume (when using Epson iProjection [Windows/Mac]).
