If you ever need to stop all the sounds playing in flash using ActionScript3, you can do so using the following method.

First include the SoundMixer class:


Then to stop the sounds call the stopAll method:

  1. I am SO THANKFUL for this simple explanation. I’ve spent days trying to figure this out and this was exactly what I needed. The new and improved “stopallSounds” for the AS3 newbs!!


  2. Me too! As the manual didn’t take me anywhere with manuals
    obviously at fault then seeing most people looking for a solution
    to start and stop sounds failing I was relieved. I would still like
    to see a working solution with the SoundChannel object where the
    stream may be stopped and resumed.


  3. I flippin love you. Thank God I found this. I’ve been working on this since 2pm and it’s currently 1:26am, that whole time I’ve been trying to figure out how to stop overlapping sound. Thank you, thank you, thank you!!!!!!!!!!


  4. Doesn’t work, i have my sounds imported through AS3 i have images, 1 frame long and you can navigate by buttons to the next frames.. i have 5 of those frames, and every frame has his speech. But after i had the 3th frame, and enter the 4th frame the sound of the 3th frame alsof plays, and i can’t stop this.. i don’t know how to stop that sound of the 3th frame 😦


  5. I have place the soundMixer.stopAll() to stop the all sound but its not working.
    I have loaded the sound dynamically. beside stopAll method is there a any other solution to stop all the sound which are playing in swf.


  6. To mute all sounds use :
    SoundMixer.soundTransform = new SoundTransform(0);

    To unmute all :
    SoundMixer.soundTransform = new SoundTransform(1);


  7. How can it be that simple! Ha Ha. Yeah I am in with everyone else. I wanted to stop all the sounds so I created a for loop with the channel to stop everything added to the channel and that didn’t do any good. Blah! thanks for the 2 lines of code 🙂


  8. Any solution to stop sounds if the user leaves the frame while the sound/video is still buffering? This doesn’t work in that case. Thanks!


  9. when i use this SoundMixer.stopAll(); in my movieclip code to stop mixing each frame containing sound it works but it also stops my bg sound that i have code in my document class.

    so please can u help to avoid this problem.


  10. Is their a code to start all sound for a video that is just looping. If I add the code to stop, when the cartoon loops the audio does not restart.
