Unable to locate Rhythmic pounding sound on map

Hey Team,

I have the strangest sound on my map and I cannot locate what is causing it for the life of me. It is a rhythmic pounding sound that plays maybe every second or 2 and spans the entire map (does not matter where players are).

Is there a way to locate all sounds in the map for me to investigate?
I am assuming it is coming from some prefab that I imported so if not Ill just have to delete items 1 by 1

In your outliner you can search for sound devices.
Search for Radio or Audio Player. Hope that helps.
