I'm testing this new repository "Record Audio" for Moodle 2.9. I have installed without problem. I have enabled management repositories. I made a test within a course, adding a file, and when I go to select a file and select the repository "Record Audio" I left with the message "Loading. Please wait" and the two buttons "Cancel" and "Upload" and stays there without being able to do more.
I tested in all browsers and version that is running Flash Player is the latest.
Attached screenshot where you can see how it behaves.
