I challenge you to kill my mp3 stream

Could anybody tell me if there is a way of killing an mp3 stream.

I have three buttons, each load an mp3 into a unique sound object (for reasons of using a unique sound position property). I click on one button and it begins the stream, I click on another button before the first stream has completed and the new stream starts, however I have noticed whilst testing this that the first stream did not stop.

I have tried:
• stopAllSouns();
• delete soundObj;

They do not stop the stream. This will cause a problem and clog up bandwidth quickly. For example, if a user quickly clicks through all three buttons, three streams will be running simutaneously.

Thanks in advance
