My receiver's remote control broke about a week ago, so I went out and bought a new universal remote. But it does not have a code for receivers. I have the receiver connected to my Sony TV, Yamaha CD player, and Xbox. I found codes for the TV and CD player, and they work off of the remote now. But I want to be able to use the remote to switch between the three devices I have hooked up, a action that I need the receiver to do obviously. I have no clue how to get the remote to work the receiver. Thank you very much.
