If you can't hear any sound when audio is playing in a smart classroom, there are a few places to check that the volume is not muted or turned down:

  • Extron panel
  • Computer desktop
  • Video/audio playback tool

Extron panel

Ensure that the volume on the panel is turned up

  • Also check that ExtronScalerD is selected for the output.
    If ExtronScalerD isn't selected, click the up chevron on the right, and select it from the list.
