Audio breaks for fraction of a second when changing the slide
I have a powerpoint presentation.
I imported a single voiceover file (with loop music in beginning & end) across entire presentation (in presenter '13)
Then through audio editor I defined slide transitions. (And then synced animations). I did this in Presenter '13 and then imported presentation to storyilne.
First four slides have continuous loop Music, which eventually fades and then voice over starts.
My problem is that when I publish it from Storyline and play the published presentation, during first 4 slides during each slide transition, audio breaks for fraction of a second and then continues. This happens for each of the 2nd, 3rd and 4th slide.
After first 4 slides, I have no problem since voiceover pauses for a second between slides.
Can you kindly help me fix this problem? All I want is continuous Audio in its original form without any breaks.
