Hi Gordon,
I have been trying to get an audio player called "dewplayer" to work on hotpot. The player appears in the exercise but when you click on the player there is no sound. It works fine outside moodle environment (i.e when I test the exercise in my browser). Also can get it to work in the "files" part of moodle, but not in the actual course page. I have taken the liberty of uploading a sample to your server at:

Your help would be appreciated.
Cheers,
Robert
