How to add Sounds to Set speakers on level

Hey there- i’m a new user to UEFN so it’s a HUUUUGGGGGGEEEE learning curve for me. i used to design,edit and Test mods for GTA3/VC/San Andreas back in the day but this is very huge step for me.

I have built a Festival style level where i’ve got massive speakers but when i load up Fortnite- i get no sound from them.

How do i tag the speaker with a sound? is it a part of thr Verse programming?

Is it possible for a player to change the sound such as use of radio mechanic in a car/truck??

how do i get the Verse window up haha-see complete beginner

This is what i’ve built so far- i would love to build a multiple scenario map,please be kind i am a Noob when it comes to level design haha
