Box trigger and Sound

Hey all im new to unreal engine so take it easy…

I recently created a box trigger, added sound through the matinee and when i walk through the box trigger the sound plays and when i walk out of the box trigger the sound stops thats what i want.

The problem is, once i walk out of the trigger and walk around the environment and walk back to the box trigger and through it i cant hear the sound again. Although when i look at the blueprint while walking through its executing but im not hearing anything.

Is there a way to have the sound always play whenever i walk through the trigger and hear it (only hearing it once) for a countless amount of times ?

i have attached a screenshot of my blueprint etc

thanks

Dont worry i found my answer after a bit of a play around, i just had to select the Rewind on Play option.
