Want to fix my head set

I play on my Xbox Series X and I recently bought the Turtle Beach Recon Chat and while I can hear Xbox parties and fortnite voice channels, I can't hear any game audio so I was wondering if there was a way to fix this. I know about the chat mixer but on series x, that just changes how much the background noise is filtered out. I want to know how to make game audio go into the head set, not the speakers . I don't see why background noise has anything to do with it
