Slide audio (VO) does not load, or load properly in published projects

Captivate 7.0.1.237

I’m having problems where slide audio (VO) does not load, or load properly in published projects. This is random, meaning it could be any slide or slides, and going backward to the previously viewed slide could fix the problem.  It could be just the first few words on one slide, the entire slide or multiple slides in a row.  I’ve tried various compressions and currently have things set to use optimized slide quality, NO advanced project compression (unchecked) and 64Kbps audio.  I have the pre-loader set to 10%, but have tried 20% with the same results.  Note this is a 350 slide project with 157 slides having audio.  Does anyone have any sound (no pun intended!) advice?

    As much as I now believe that placing an Action on a slide of only .2 seconds is NOT a good idea, moving the Action to the following slide did NOT fully remedy the problem I was experiencing.  After extensive Beta testing, I still had reports of slide audio missing the first few words of a sentence or not playing at all.  I don’t consider myself a “power user” of Captivate, but have produced nearly 20 programs over the last 3 or so years without this problem.  The one difference of this latest program was project size – 13 randomly accessed modules with a total running time of about 40 minutes.  Previously I always placed .wav files in my projects and let Captivate do the compression.  With this latest project, the .wav files simply made the project too hard to work with, so I compressed them into .mp3 format in Audition before placing into Captivate.  I noticed however that if I made any adjustments to audio (timing, etc.) using Captivates internal audio editor, that Captivate saved my changes back as .wav files (in the library).  Okay, I understand why, but it seems that’s where my problems began.  So… as Rod Ward suggested I reinserted ALL the audio.  My workflow was: 1) open the original .wav file in Audition, 2) make any changes found necessary during the programming process in Captivate, 3) save the .wav file as .mp3 in Audition using a new name, and finally 4) reinsert the slide audio in Captivate.  Problem solved.  Bottom line, for me at least, if I’m going to insert .mp3 audio into Captivate, I won’t mess with it once inserted!  One other possibility would be “round-trip” editing of an .mp3 file in Audition directly from Captivate, but have never tried that as recompression of an .mp3 (I believe) would be ill-advised.

    Again, thank you for the advice and support!

    That is a big project, audio clips tend to increase file size a lot. Did you start the audio clips little bit later than beginning of slide, and end bit earlier?

    Yes. I inserted the slide audio (VO) at between .4 and 1.0 second, depending on the previous slide's content. And always left at least .1 to .3 second at slide end.  Watched both very closely.

    I'm sorry, don't have any other suggestions. It must be the loading of the audio clips that cause the problems.
