Audio issues can be caused by several different factors. Rule out the simplest ones first.
Try this solution
- Crestron control systems include a No Sound feature; when selected, this will be indicated on the control panel. Press the No Sound button to deselect; the indicator will disappear, and the sound should resume. Use the Volume menu to adjust the audio level.
- Select the correct input source. For classrooms with multiple monitors or Dual Image capabilities, audio will come from the last source selected. Reselect the source for your audio, and the sound should resume.
- Find the speaker icon in the computer's taskbar (bottom right for Windows; upper right for Mac). A slash or X indicates muted audio. Select the icon to open the sound control and unmute. Use the volume slider to adjust the audio level. If the speaker icon does not appear, try signing out and back in.
- Check the audio controls in the application or website; the sound may be muted or turned down.
- If these steps fail to resolve the issue, restart the computer and try again.
