and does't work. can me, please? update: posted full code. use flashdevelop 4.6.4, flex4, sdk 4.6, flashplayer 11.1. mean if streamrcv soundtransform volume greater 0, sound "on", doesn't change silder "rcvvolume". if streamrcv soundtransform volume equal 0, @ first, video have no sound, if drag slider, sound volume controlled normally.

on flex, play video stream can use videoplayer or videodisplay components or video object netstream.

this minimal working example of how use theses elements live stream , how adjust sound volume :
