You could hide them by CSS, ie you could hide all the controls like this:
.jp-controls { display:none; }
or you could hide individual controls by their ids
.jp-controls #PlayLink, .jp-controls #PauseLink { display:none; }
if you don't want to hide them globally but only in a specific instance then add a custom css class in the settings for the instance and then further qualify the above rules by preceding them with .customclass where customclass in the class you set in the settings.
Hope that helps,
