I have an apple tv hooked up to one of the hdmi inputs on my denon 2112ci. When listening to music on the apple tv, I want to be able to hear music in zone 2. It will nit let me send the apple tv to zone 2. Why? Is there any way to get this working? I read somewhere you cannot send hdmi devices to zone 2 but nit sure if hat I read is correct. Any help would be appreciated.
