Temple Bells: Gong

Selecting the Gong scene setting in the Temple Bells plays something that seems it would be headphone only, but if your screen goes off and you turn it back on, then continue to play, it reverts to another setting (in my case, the Balinese Temple setting, but I am not sure if it's always that one of if it's just that one because that was the last one I used prior to the Gong scene).
