One of our Music instructors has created a New Quiz with m4a audio clips.
Some quiz questions contain a proper iframe URL linking to the course Files@PLUGINFILE@@ links with no closing bracket.
The audio is playable for some users but not others, and it seems to be browser and OS independent e.g., a Mac user can play the audio files in Firefox while some Windows users can play them in Chrome but not Firefox.
@PLUGINFILE@@ links can be downloaded by right-clicking them.
Has anyone seen this behaviour before?
