Publish to? Slide audio, background audio, object audio? If it is slide audio, did you try to have the audio clip starting little bit after the start of the slide and ending bit before end of slide (sorry, that is one of the standard answers )
Sorry, i knew i was forgetting some helpful detail... All of the audio is slide audio. Yup, I tried that. I've worked a lot with Presenter in the past and I've learned that trick. This is garbled throughout the 200+ slide demo. I did discover the fix, however. Maybe this will help others: I had checked the box indicating that I wanted the audio mixed to a mono channel when published (I thought it would make for smaller file size). That was the issue. When I removed the check, the audio problem went away.
Thanks for posting, although I find this strange. But of course for VO I always start with mono, never create stereo.
