Not hearing sound in classroom

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

  • Extron panel - ensure that the volume on the panel is turned up.

  • Computer desktop -
    • Click the audio icon (bottom right, next to the date and time) and ensure that the volume 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.

  • Video/audio playback tool - check the volume in the app that is playing the video (YouTube, embedded videos, Windows Media Player, VLC or PowerDVD).
