I have a few external audio clips in MP3 format that I bring in to my SWF by creating different Sound Channels for them. However what I would like to do it when the end of the MP3 file is reached, it will dispatch an event to make the playhead on the main timeline move to a certain frame. Is there a way to do this? If so, con someone shed some light on the subject for me?
