Audio on Layers when you revisit

Hmm.  At this point, troubleshooting is just guessing without seeing all the programming. Someone might be able to solve the issue if you upload the .story file. Here are the best practices for doing that:

Only include slides that are related to the problem.

Be sure objects, layers, motion paths, and variables have meaningful names.

If there is proprietary content, replace or delete it. For example, replace proprietary text with “ipsum lorem” text.

Of here’s some standard advice that the staff usually offers:

• Be sure you only work on Storyline files located on your local hard drive.
• Quit Storyline and relaunch it.
• If that doesn’t help, try to repair Storyline. See

If all that fails to help, submit a case directly to the Articulate staff. You can do that here: https://access.articulate.com/support/contact
