Stupid Sounds Problem

1

OK… well i want to play a sound 5 times but not by using

my_sound.start(0,4);

but by making it play until a variable =5;

function my_start(k:Number) {
	i=1;
	while (i<=k) {
		my_sound.start();
		while (my_sound.position==my_sound.duration) {
			//wait until the sounds stops playing
		}
		i++;
	}
}

the problem is… plays the sound twice if k is greater than or equal to 2…if k is 5 it plays 2 times… the first time is normal and the second time plays 4 times at once…why??
PS: I do not want to use Interval(…) as well…
