audio player issue – no playback


I have an issue to resolve with wordpress, unrelated to plugins. I am using the wp audio embed in a page which has things set-up in particuliar way. I was able to find the part of the theme where I could put the do_shortcode () function, and so now I am able to see the audio player that was called with the shortcode. My issue is that the audio is not playing back? Can I get some advice on this issue? site link is here bottom right corner to open the info box.
