Can I stream music from my iPhone thru my appletv then thru my tv speakers?

I have an Apple TV hooked up to my router and to my whole house receiver. I want to stream music from my iphone5 to my whole house receiver thru the Apple TV but I can't get the remote app to find my home network. Do I need to have a computer with iTunes hooked up to the network for this to work or am I missing something.
