I can not hear any audio while sliding the red pointer over timeline in editing mode. Although it is audible after i export the movie. Help!

It might be a mute point but I had this problem as well, and I just figured out how to fix it. In the properties window of flash for the audio file change the sync setting from event to stream. This will make it so that audio plays while you scrub through the time line.
