Although the files in the Sounds folder will play in ActivInspire on a Mac, the sound files under Subjects>Music>Musical Notes will not. We can see it “playing” through the Sound Controller but nothing is playing. All volume controls are up and other sounds are playing, just not these ones. The only difference between these files and the files in the Sounds Folder is the file type. The ones not working on the Mac are midi files.
I was able to get them to play outside of ActivInspire but not in ActivInspire.
