controlling audio in a loaded swf

Jan 23, 2009 6:49 AM

I have several flash swf's that are about 10 - 20 min. each. I load these in a player that I have created as the user selects them from a menu in the main swf (a swf player basically). I can pause start and stop the swf's with no problem, but I can't seem to get a handle on controlling the audio. I have the audio in the loaded swf's timelines because I need to sync the audio with the animation taking place in those swfs. I COULD, take the audio out of the timeline (after syncing it), and then load it seperately, but it would be much cleaner for me to just have it in the timeline. I've resorted to the SoundMixer of the main swf to mute and change the volume, but I can't get hold of the Sound(), soundTransforms etc. of the loaded swf. To assign a play location for the soundChannel I need to access the loaded swf's Sound().Play() function, but I can't seem to do that. I have exported the timeline audio in it's actionscript, supplied a name (same as it's class name), and then tried to access it, but I can't seem to do it (yes I wrap the loaded.content variable in a MovieClip cast--that's how I can control the pause and play of the animation).

Tutorials I have found only seem to work with sounds loaded into variables, and none refer accessing timeline sounds in a loaded swf.

Has anyone done this before?

Thanks for helping

    it seems as thought you only want to 'stop' and 'start' the sound on the timeline, correct?

    in that case you should be able to call:
    SoundMixer.stopAll();

    from the parent swf, when you call the playhead to stop as well. then once the playhead is initiate again the sound should start playing automatically.

    Thanks for helping out. I think you are correct about what I want to do. Just to make sure though, I also want the audio to pick back up where they paused the animation if they hit the pause button.

    I've tried SoundMixer.StopAll() but do not get the results I am looking for. The audio starts for about a half second, but then shuts off (almost what I want on load, but not quite). Then when the play button is pushed, the play function is triggered, but no audio comes out. When the stop function is called, the audio starts again. This is very strange to me. I have my code posted below.

    Again, thanks for your help.

    i think that you may want to place a stop() action on the first frame of the movieclip's timeline, rather than doing so in the event handler, this might help keep the file from 'beginning' to play previous to the command to do so.

    add the SoundMixer.stopAll(); call to both the pauseMovie and stopMovie methods.

    make sure that your timeline sounds are set to 'stream' (properties panel)

    This is working much better. I had tried using stopAll() earlier, but because it wasn't set to stream, it did not work correctly. This made me think I had to dive into the swf and set sound(), soundTransform() etc. The stop(); in the first frame didn't seem to do the trick for preventing the audio from starting up, but I moved the audio one frame down, so the stop() is now executed before the audio in the swf and that does it.

    Thanks so much. It's nice to see a very simple way to solve this.
