I cant seemed to replace the sound image that appears when viewers see the pdf online. It becomes a play button and I want to have my own icon. My next idea was to make a button and put it on top. But the buttons can only be set to play OR pause. Not both.
What can i do?
We cannot add poster to sounds in published documents, you can try one thing and see if that works for you. As you mentioned you can add a button and add an action of playing sound, similarly you may add one more button below play button and add an action of stoping/pausing sound. Add 'Show/Hide Button' action to both the buttons, on click of which hide itself and show other one.
