Sound Issues - MP3Loader & Child swfs

Recommended Posts

hi again,

I'm experiencing sound issues with MP3Loader when loading a series of child swfs sequentially.

In this example, I'm loading 2 child swfs from Parent swf at once and playing then sequentially. Each child swf has it own MP3Loader’s with both autoPlay methods set to false. So far, the first Child swf plays first and when it completes the next Child swf starts as it is supposed to do.

However, when the first sound plays from the first Child swf so does the first sound from the second Child swf at the same time. I don’t know how to stop this sound from playing until it should.


The other related issue is the when the first Child swf is load for the second time, because its set up to play in a loop, the first sound isn’t being reset so that it doesn’t play again as it should.


Here the code from one of the Child swfs.

I've looked over the 200+ lines of code above and your attached files.


The only thing I can guess is that the mainIn TimelineMax isn't paused so it plays as soon as the swf that it is in has loaded.


Other than that it is really difficult to visualize how all that code is supposed to work. The only thing I can suggest is that if you need more assistance you are going to have to provide much simpler files that focus on illustrating a singular issue. Although that is not an easy task, more often than you will solve the problem while trying to recreate it without a lot of additional logic and code baggage.

Hi Carl,


Thanks for having a look.

I was sort of hoping you might have found a glaring problem & a quick fix so I wouldn't have to strip it back but that was just wishful thinking!


I tried pausing that mainIn TimelineMax instance however it just meant it didn't play at all. The issue does seem to be related to the loaded sound files only because the mainIn TimelineMax instance in the 2nd Child swf loads in and plays just fine after the 1st Child swf's TimeLineMax animation is completed. So again it seems to be the way the sound is loaded in or set up that is triggering the sound to play prematurely from the 2nd Child swf.

But I appreciate your time & efforts.


I'll see what I can do.


Thanks again.
