3D Sound continue after fall-off?

I’ve read this thread : How can I resume an out of range sound when the player comes back - Audio - Unreal Engine Forums
It states that I have to assign the sound to a class and set the class to ‘always play’.

Even then, when I leave the fade-out area, the sound simply stops playing… When I go back it doesn’t play…
Help?

Bump anyone? I really need to get this working…

And bump again!

Still haven’t resolved it…
