Hi Deborah,
Thanks for sharing what you are experiencing with the volume across your project.
When publishing, I'd recommend the 'optimize audio volume' option to see if this helps the inconsistency. It's designed to assist in balancing volume across your course, as you can see in our documentation:
- Mark the Optimize Audio Volume box to normalize audio throughout your course for consistent volume across all slides.
It is audio only and does not include the audio within video files.
If this doesn't fit the need or the video audio is the main culprit, you'd need to adjust them individually.
