Hey everyone, My goal is to be able to play audio through my home stereo while using the atv4. My tv and receiver and atv4, connect perfectly. Sound even plays through my receiver. However, I can't control the volume of the receiver with the remote. Additionally, if I just connect my atv4 and receiver, I can hear the boot up sounds of the atv4 and then I can control the volume with the remote. So I can confirm the receiver is CAPABLE of being controlled by the remote. Not sure why including the TV in the equation would render the remote unable to control the volume of the receiver. All my devices are connected by hdmi. My tv is only a few months old and my receiver is only a few yrs old. Anybody know how to fix this??
