Adding Sound to Matinee (ADVANCED)

Needing a little advice, i will try to explain this the best i can keep in mind i am new to UE4.

I have a box trigger near a button, once your character enters the box trigger you can interact with the button by pressing the E key, after pressing the E key the “reactor core” fires up using matinee everything visually is looking good and animates the way i want BUT the issue is i need my “reactor core” sound to play aswell and stay looping until your character decides to turn the reactor off “pressing the E key again” also i know some basics on using sound cue’s, i favor attenuation it seems to make things more realistic in my case having the sound fade when walking away so thats no issue. what im looking for is a way to have a sound cue near the reactor that has attenuation and only activates when pressing the same e key that activates the reactor animation and the sound remains until e key is press again.

Sorry for explaining this twice, i really hope there is someone out there that can help me out, your time is much appreciated as i know time is precious, this has me bummed out and searching high and low all over.

p.s. when i try to add my sound to matinee as >new empty group >new audio track it only adds a small portion of my sound file at the same length of the animation, if i drag out the timeline just to play the audio, it feels like something is duct taped together half as*ed, also no attenuation feature in matinee -_-

im a greenhorn in UE4 but this engine is what im sticking with it offers everything i need and more, not to mention an amazing community, resources, and beginner assets to get your feet wet and on your way to being a UE4 ninja.

Since you are using an input event to fire the Matinee you can use that to Play a sound actor as well. Drag & drop your sound asset into the level(disable Auto Activate in Details panel) where the reactor is, then in level BP get a reference to the sound > Play. And when you stop the reactor just call the Stop function. You can override attenuation by filling the checkbox in the sound’s details and give it any realistic effect you like.
