There is no sound. What should I do?

• Try the following:
  • Press the button on the projector or remote control to increase the volume.
  • Make sure A/V Mute is not enabled. (The A/V Mute button on the remote control may have been pressed.)
  • Make sure the A/V mute slide (lens cover) is open.
  • If you're using a DVD player or other video source, make sure its volume is not turned all the way down or muted. Also, make sure the cables are connected correctly. See Playing Sound Through the Projector.
  • Try adjusting the Volume setting in the Settings menu. See Customizing Projector Features.
  • Make sure the audio cable is connected securely at both ends. For computer audio, connect the cable to your computer's headphone jack or audio out jack.
  • Make sure the volume control on your computer is not turned all the way down or muted. In Windows, you may be able to use the volume control in your Windows system tray (lower right corner of the screen). On a Mac, you may be able to adjust the volume from your menu bar (top right corner of the screen) or via the volume control function keys.
  • If you are using the projector's internal speaker, make sure the EasyMP Audio Out option is set to Internal in the projector menu.
  • If you are using external speakers, you need to set the EasyMP Audio Out option to External. See Connecting External Speakers or Customizing Projector Features for more information
