I have created a clickable in a particular slide and linked other slides to the clickable. But, even before the clickable is clicked audio of the corresponding clickable linked slides automatically starts playing without stoping till all the slide audios are done.
I don't know what you mean by clickable, but following my intuition will try to give you a possible solution.
You probably use 'slide audio' which has its timeline visible under the slide timeline in the Timeline panel. If you don't provide a gap before and after the audio timeline, it is possible that Captivate 'sees' all audio as one long project audio clip. It will be loaded at the first slide with audio and continue to play
Please leave a gap:
In that situation each slide audio will be loaded when entering that slide, and your issue may be solved.
