I am not seeing the bug with this simple code:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
horizontalAlign="left">
<mx:Script>
[Bindable]
[Embed (source="../assets/jazz.mp3")]
public var soundClass:Class;
</mx:Script>
<mx:SoundEffect id="mySound2" source="{soundClass}" duration="20000" />
<mx:Button label="playMusic with no pan set" mouseDownEffect="mySound2"/>
<mx:Button label="pause sound" click="mySound2.pause()" />
<mx:Button label="resume sound" click="mySound2.resume()" />
</mx:Application>
If I play, pause and then resume the pause, the SoundEffect seems to
do the right thing. If you have another scenario where pausing the
SoundEffect doesn't work, please file a bug at bugs.adobe.com/flex.
