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

• Try the following:
  • Use the Volume buttons to adjust the volume (see Controlling the Volume), or adjust the Volume setting in the Settings menu.
  • Make sure A/V Mute is not enabled. (Press the A/V Mute button to disable it.)
  • If your presentation includes computer audio, make sure the volume control on your computer is not turned all the way down or muted. In Windows, you may be able to check this by clicking 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.
  • Make sure the audio cable is connected correctly. See Playing Sound Through the Projector.
