Users can select the ability to place audio on the page via a play/stop button only instead of showing the player controls.
To upload and add an overlay file to your publication, please see the following guide:
Once you have uploaded and select the MP3 from the Source File menu, your overlay editor should look like this:
Selecting the tick box Playerless Audio will provide you with two more drop down menu's, first to select the play button and the second to select the stop icon displayed. Once you have selected these, hit Generate playless audio controls will give you a new icon (the play button you selected) to place on the page.
Ensure that once you have positioned the play button on the page that you finish by clicking Save All in the bottom right to save your changes.
