Audio dropping on two slides in live version of course only

We do not usually export using SCORM.  Our LMS uses mainly AICC.  That said, we have never been able to solve the issue of audio dropping out.  The best we've been able to do is to work around the issue by splitting up audio into multiple segments, which makes slide timing a bit more difficult.  You may notice that the pages that have the audio issue where the exported content goes silent, that the actual audio track experiences a very brief digital "chirp" in the sound, even though that "chirp" was not present in the original recording.  This anomaly coincides with the audio drop on the page.  Even more frustrating is that when you make a new recording and eliminate this mysterious "chirp" another chirp is likely to appear in another audio track on another page, effectively dropping out the audio on that page. This has happened so frequently for us, I call it the audio-chirp "whack-a-mole" stage in course publishing.

I believe that there is some sort of error in the code that causes the recompression of audio file when it stores it inside the Storyline story file to cause these digital chirps to appear, but I can't prove it, so I have to just work around it.  It makes working with audio very stressing, since there don't seem to be enough people having the problem for it to be taken as anything other than user/LMS error. :(

Best of luck to you!
