wordpress audio bar does not show

During one of our plugin or theme or wordpress upgrades, our audio bar disappeared. It shows in the edit mode and it plays on a website page where we've designated "auto play", but it cannot be seen or controlled by those visiting a page. It worked before and we haven't changed anything that we know of that should impact this.
There are three places in the middle of this page that should have audio bars:
code used is:
<p id="text">Grandma sings Hickory, Dickory, Dock in English:</p>
[audio mp3="http://mygrandmatime.com/wp-content/uploads/2014/05/5-21-14-HDD-audio.mp3"][/audio]
There are some notes at wordpress that indicate this could be a problem with the footer or a conflict with an update that has changed "visible" to "not visible".
Any help as to what to do and where to do it would be wonderful.
