Sound Problems

Make sure that the set-top box is correctly connected to your projector.
The screen is fine, but it does not play any sound.
• If you use a set-top box, there will be no sound if you have set the volume of
the set-top box or your projector to 0 or enabled Mute. Set the volume to an
appropriate level.
