I can successfully run audio on a slide transition and can trigger audio on its own without a slide transition by using a duplicate slide. (First slide has no audio, duplicate has audio embedded or linked to and has no transition)
However, having triggered the audio is it possible to let it run across several slides ? Ideally if running the presentation through a sound system I would like the audio to not stop on the subsequent slide transitions so it could be faded out manually. At the moment I can’t find a way of the audio not stopping when the next slide is triggered, either manually or timed.
