What's the best practice for stopping looping sounds played during an animation?

Question

If I add a looping sound to a looping animation (the walking animation of a small octoped robot for example) what is the best practice to stop the loop? i could add stop events for the sound to the start of all of the creatures other animations but that seems a bit fiddly. Is there any usual approach for dealing with this? The engine I'm using is UE4.

Thanks in advance.
