This problem most likely comes from the fact that sound is playing through the data projector mounted on the ceiling as well as the room’s speakers. Simply turn down the sound on the data projector. Look for volume controls:
- on the data projector itself
- on the handheld remote control for the data projector or
- use the remote control's menus to turn down the volume on the projector
If none of these solutions remedy the problem, call Media Services at (262) 551-5950.
