Play audio on loop while animation sequence is active?

Hello Everyone,

I’m trying to activate a sound file I have set to ‘looping’ so it is always active when an level animation sequence is activated. I am using the ‘isPlaying’ node for the Boolean condition for the while loop but it seems to crash every time the loop is initiated.

I just want the SFX to play every time the animation is in motion, I have a shutter moving up and down and the player may reverse the animation halfway so the sound needs to keep playing rather than resetting.

Here is my current blueprints, I don’t know what is wrong, any help would be very much appreciated!
