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:
- Launch QuickTime.
- Click on Edit | QuickTime Preferences.
- Select Audio.
- Change the music synthesizer to Promethean Audio Device, Promethean USB Audio or USB Audio Device. The option will vary depending on your hardware.
- Click Apply and then OK.
You will now be able to hear sound playing through the ActivBoard speakers.
