Check if the Mute Sound
button is ON. Click on Settings
button for the Settings window.
If it is Off, or you turn it Off and you still get no sound, then please provide some more details about what you were doing, where abouts in Lumion etc. For example were you adding Sound Effects
as background, playing a movie with sound etc. The more details, the easier it is to evaluate the problem
