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:

  • Adjust the projector's volume settings.
  • Press the  mute button on the remote control to resume audio if it was temporarily muted.
  • Press the  A/V mute button on the projector remote control to resume video and audio if they were temporarily stopped.
  • Make sure the Audio Out Device settings are correct.
  • Check your computer or video source to make sure the volume is turned up and the audio output is set for the correct source.
  • If you do not hear sound from an HDMI source, set the connected device to PCM output.
  • 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.
