Implementing canplaythrough in SoundManager2

I need help making an algorithm to detect that all the conditions for HA开发者_开发技巧VE_ENOUGH_DATA are met (and continuously checking until they are met) and I am stumped as to how to calculate all the necessary variables using SoundManager2's whileloading option. I don't need code, just a general algorithm that would work (even pseudo-code is fine).

It turns out that setting the whileplaying option is a more optimal and simple solution. This is my whileplaying solution:

function () {
 aSound.options.whileplaying = null;
 if (paused) {
  aSound.stop();
 }
 onCanPlayThrough_callback_here();
}
