How to set sound category to hear the background sound (Unity3d, FMOD).

Hello, I'm noob in objective-c and xcode.

I need to send sound category properly so user will be able to hear a background sound while Unity3d application is running.

I'm try to override method willFinishLaunchingWithOptions but it is not working.

Can somebody tell me what am I doing wrong?
