There is no sound. What should I do?

• Try the following solutions:
  • Adjust the projector's volume settings or press the volume button on the remote control to turn up the volume.
  • Press the A/V Mute button on the remote control 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 and the audio output is set for the correct source.
  • 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 labeled "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.
  • 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.
