Level Audio Trigger not working?

I wonder if anyone can help find the fault as to why my audio trigger is not working:

The sound asset has been dragged into the level and had its volume multiplier set to 0.0 whilst its in there to stop it from playing right from the start of the game.

For some reason if I set it to 1.0 it works from the trigger but also unfortunately after a few seconds works when the level starts too.

Any ideas?

Did you check if there’s any actor in the scene that is accidentally triggering your TriggerBox?

No there wasn’t!

For some reason did a recompile and it all works!
