Question
How can I get my sound to work in a smart classroom or conference room?
Answer
Check these suggestions if you are having trouble getting audio to play in your classroom.
IF THERE IS NO SOUND:
- Is there an amplifier in the room? Rooms with ceiling speakers generally will have an amp, rooms with wall mounted speakers may not.
- If there is an amp, make sure it’s on. There will be a green light above the power button on the front of the amp.
- There are two volume controls, one master volume and one labeled for each individual device connected. Make sure that neither of them is turned all the way down.
- Check the volume on the laptop and make sure it isn’t muted.
- Check the volume on the video being played.
- If there is a touch screen in the room, make sure the volume on the touch screen is up and the sound isn’t muted.
- Try turning the volume up. Sometimes even if it isn’t all the way down it’s too low for a particular video.
IF THE SOUND IS COMING FROM THE LAPTOP RATHER THAN THE ROOM SPEAKERS:
- Some laptops display a screen to select what type of device is connected when you plug in an audio cable. Make sure that this window isn’t hidden behind another window waiting for a response.
- If using Windows, check the Sound Control Panel. Crestron should be selected as the playback device.
- If using MacOS, check the System Preferences->Sound and make sure that HDMI is selected on the Output tab.
