How to start and stop audio with input touch enabled

Hello all, I created a widget in bp and enabled the “On Input Touch Begin” event so when I spawn my BP placeable object in AR space the widget is there and I can interact with it. I the widget setup so that when you touch it and audio starts to play my issue now is trying to all a user to stop the audio at anytime. I’ve created and “On Input Touch End” event but that doesn’t seem to work and more than likely something im doing wrong. So if anyone has an idea on how to solve this issue of mine please let me know.
