Mp3 player extension has music overlaying sound on the Connect meeting recording

I installed the mp3 player extension into Connect from the Adobe extensions site and it worked fine. Once the Connect meeting started I minimised it the pod with the mp3 player in it and there was no audible sound. But now when I go to the recording the sound is playing. It plays even when you have paused playback on the recording, so it is not in the recording itself. How can I stop it from playing while I view the recording?

thanks
