Timeline audio control?

Hi i’m developing a cd-rom that needs to have the voiceover and animation sync’d… so the only way to ensure this really I believe is to place the audio voiceover in the actual timeline, instead of loading it into a sound object from the library… So, my question is, is there anyway to control the sound of the timeline audio?.. is there a global sound volume control, such as an fscommand or something (since the cd-rom will be running it as a projector). I’ve looked around and its difficult to find an answer on this, as most people suggest using the sound object, but in this case that’s probably not possible unless there is some tricky actionscript that could force it to sync to the timeline and framerate. (of course there’s the concern there that on slower computers that solution wouldn’t work)…

so if anyone can help me work this problem out that would be great, thanks!
