When you say "images", do you mean still photos?
Have you resized all of the photos to no larger than 1000x750 pixels, per our recommendations?
And have you ensured that your audio is a WAV file?
You may also want to render your timeline (press Enter) before playing it back.
Could you please detail whether or not you are in the process of creating an Instant Movie and your audio problems
occur in trying to do that?
Or does this applies to all non Instant Movie matters with your Premiere Elements. What version of Premiere Elements are you using and on what computer operating system is it running?
These tips fixed my problem.
