Playing one sound while stopping the others

programming flash

Hi, I’m stuck while trying to playing some sound and stopping the others.
What I do is : I’m using a linkage to get access to my sound. For example I have 5 linkage sound. I need to play just one specific sound and stop the others. I create a new Sound() and a new SoundChannel() for each one , and put it all in Array.
But when I’m trying to stop the others by stopping it’s channel, it won’t work:
The snippet is somewhat like this :

for(i=0;i<song_.length;i++)
{
       if(snd==song_*.clas)
           song_*.sound.play(0, loopz);
       else
           song_*.chanel.stop();
}

I have an array of object that have a sound and channel for each one.
Anyone could help?
tHx for any.
