Stop currently playing audio when starting a new audio clip to prevent overlap?

Hi there! I have done a lot of research into this problem, and haven’t found anything that works. My issue is that I use the script made by Brackeys in his audio manager tutorial found here:

I use it to manage the different audio clips of narration throughout my game. The problem is that I need to be able to tell if a narration clip is already playing before starting a new clip, and if it is then to stop it and play the new clip so that the two do not overlap with each other.

Any help is greatly appreciated,

Matt
