Unity Audio

Hey guys, I need some help and tips. So currently my team is working on a project in unity, for live a show. So what I am trying to do is setup sound in my environment for like surround sound using 5.1 or 7.1. We have surround sound setup using a audiofire system. Only problem is that we have a SMPTE track that plays and I am trying to find a way to have it play in unity but not be heard along with other sounds...Does anyone have any tips or tricks on how I can do this? anything will help thanks!
