We didn't get any sound today!
All the other software we used played sounds correctly, but Tonic Tutor didn't not play. My student was so disappointed! ;-(

It's possible that the game was muted. If you look at the bottom left corner, there should be a mute button and a volume slider. If the mute button is red or the slider is set all the way to the left, all sound will be muted. This setting is associated with the account, so if sound is muted in one game, that same setting will be used in other games until the setting has been changed. If it doesn't look like sound is muted, please contact me at firstname.lastname@example.org, I'd be happy to help you solve the problem.
