I am a secondary school teacher and I been given have 37 different powerpoint files, each with about 50 slides on each. Within each slide, there are animations with sounds. I want to keep the animations, but get rid of the sound effects because they are annoying. So far I just mute the computer speaker, but I would love to find a way to get rid of all the sound effects. Can anyone tell me a macro I could use to do this?
