Thanks again for your help. I tried to use the 'label' in Feedback to get the Flash audio player to show up (by linking to an mp3 file in one of the course folders) and I'm still not successful. I only see the link but the player doesn't appear. It appears when I link to the same audio file from a web page resource.
I see from your screen shot that you have managed to do it but I have no idea what could I have done differently.
