I recently discovered this very nice little application http://www.good-ear.com/servlet/EarTrainer?chap=0&menu=0

It runs well with Firefox on Windows but I have not had any success in getting any sound from its little built-in player.

I have tried fiddling with the QuickTime plugins, selecting various midi add-ons, using mozplugger plugin, JACK on/off but no luck so far.

Does anyone have any ideas that I could try to make it play?
