removeChild is not killing audio

OK, this should be an easy one. I have a video inside a container movie clip. Said movie clip is called with "addChild". There is a button that closes the video/mc via "removeChild". However, the audio from the video can still be heard. How does one kill audio along with removing of a child?

Thanks!


EDIT - I have added "SoundMixer.stopAll();" to the removeChild function. While this works, I have a feeling there is a more proper way to do this?
