FLVPlayback actionscript Mute

I’m working with the FLVPlayback component but the mute functionality is a bit of a black box to me and it seems Macromedia has forgotten to mention anything about it in the help files.

I’m trying to mute a playing movie with actionscript. The closest I got is using myFLVplayback.volume = 0. However volume 0 is not the same as mute and pressing the mute controller will do nothing and leave the volume at 0.

I can use the volume slider but I can’t stand not knowing how to mute the sound through actionscript. Any thoughts?
