<mx:VideoDisplay id="rcvVideoDisplay" x="20" y="50" width="300" height="250" volume=".9" />

And this does't work. Who can help me, please? Update: posted full code. I use FlashDevelop 4.6.4, Flex4, SDK 4.6, flashPlayer 11.1. I mean if streamRcv soundTransform volume greater than 0, sound is "on", but doesn't change with silder "rcvVolume". If streamRcv soundTransform volume equal to 0, at first, video have no sound, but if drag slider, sound volume controlled normally.
On Flex, to play a video stream we can use a VideoPlayer or a VideoDisplay components or a Video object with NetStream.
This an minimal working example of how to use theses elements with a live stream and how to adjust their sound volume :
