Thanks, that was fantastic. The code below (in my case where there is
one sound file per slide) returns the same sound for every slide. The
solution to this was to remove the sound data at soundRef from the
array. In the case where there might be more than one sound per slide
you can just check to see if you sound data array is empty after all
slides are iterated over.
Thank again!
