i am trying to build a movie using flash cc and have placed a mp3 voice over on its own layer. when i play it back as an swf file it works perfectly. however, when i go to File>export>export Video i get the .mov movie but the voice over is no longer there. any idea of what i am doing wroing?
Can you also try this -
Add a blank keyframe or a keyframe at the starting of the sound in the timeline layer. Does this help in playing sound in the exported video?
Same problem, and SujaiS advice worked for me.
I added a blank keyframe before the initial audio's keyframe, and it played.
