Faint sound whenever I play pirates

[Edward Edgemenace]

In tormenta cave, in front of that first seabeard, there is a waterfall from the roof, which causes the water dripping sound for me. Again, when I toggle "Sound Effects," (the check box, not sliding the volume) the glitch occurs, making each successive pass under that water add to the total sound playing, not going away. By leaving sound effects checked ON all the time, I can at least tell when it is starting to get wonky, then re-log when it does.
