I am using this event to initiate a looping sound (MP3 music):

The weird thing is that while this sound should loop:


THIS happens (turn volume up, had to record it with my Mac's microphone from my tablet's speaker):


The sound plays over itself and then stops. As if instead of looping it, it plays the sound over itself every MMF loop until it reaches the maximum number of sounds that can be played at once, then stops.
