How can I stop all sound in flash using AS3?

What can I do to stop all sound in my movie using AS开发者_开发知识库3?

you need to import flash.media.soundmixer, then you may run the command soundmixer.stopAll();

this should stop all the sounds.

You can try this solution as well:

var sTransform:SoundTransform = new SoundTransform(1,0);
sTransform.volume = 0;
SoundMixer.soundTransform = sTransform;
