1421 – Unable to hear sound from ActivBoard when playing files in QuickTime

Applicable to:

  • ActivBoard 300 Pro

    ActivBoard 300 Pro

  • ActivBoard 500 Pro

    ActivBoard 500 Pro

When playing a file via QuickTime, you may notice that there is no sound coming through your ActivBoard 300 Pro or ActivBoard 500 Pro speakers.

This is because of a setting within QuickTime which overrides the audio device to be QuickTime’s own MIDI playback device.

To enable sound to come through your ActivBoard when playing a sound file in QuickTime, follow these steps:

  1. Launch QuickTime.
  2. Click on Edit QuickTime Preferences.
  3. Select Audio.
  4. Change the music synthesizer to Promethean Audio Device, Promethean USB Audio or USB Audio Device. The option will vary depending on your hardware.
  5. Click Apply and then OK.

You will now be able to hear sound playing through the ActivBoard speakers.
