Probleme » Keynote recorded slideshow export to Quicktime - no audio

I have read a plethora of similar issues with users dating back to 2008. Why can't Apple get it together and fix this!

I spent almost 60 hours building, narrating and editing a Keynote presentation only to find that when I export the file to Quicktime, the audio isn't included. Its a silent film, which defeats the purpose of using this software. Is there a reasonable work around?

Please help...

I didn't find the right solution from the Internet.
