Adding audio to Simple Page

I am a bit lost as to why my audio isn't embedding into a Simple Page, but it works fine when I embed the same code into an Exhibit page. I am referencing the audio URL that was entered into Omeka using the Dropbox plugin because the file was too large for our server to upload.

<object><param name="autostart" value="false" /><param name="src" value="" /><param name="autoplay" value="true" /><param name="controller" value="true" /></object>

Does anyone have any suggestions for embedding an audio player in a better way?

Thanks for your help.

What versions of Omeka, Exhibit Builder and Simple Pages are you using?

Thanks for resonding.

I have:
Omeka version 1.5.3
Exhibit Builder version 1.2.1
Simple Pages version 1.3.1

Is there a solution without having to upgrade right now?

Have you tried disabling the HTML editor for the Simple Page?

No, I had it enabled, so your solution worked! Many thanks!
