I am trying to lower the volume on the audio file I added to a presentation but it doesn’t actually change the volume when I do.
Please follow steps as described in this tutorial https://atomisystems.com/tutorials/change-audio-volume/
I follow the steps in the tutorial. It only works on the first slide. I cannot change the volume on any of the other 25 slides.
For simple, please right-click the audio, select Play in Current Slide then apply effects, then select Player over Multiple Slides again.
