I have been adapting a Powerpoint story - adding things in to make it better. It already had some sound buttons but the ones I have added keep failing to work. I have imported them from clip organiser and they all work well initially. I have saved the whole thing and that seems to be when they go - they still appear on the slides and in the animation listings but just do not work either automatically nor by clicking on the actual button. It's very frustrating - I was SO pleased with myself! and I've tried re-loading them several times but it's very time-consuming and still failing ... hoping someone knows WHY this is happening! Fingers crossed - thanks!
