KeanoneI thought that you also can add speaker 2 as default on apple tv (hdmi1) in advanced settings
I have looked for a way to do it when changing the audio mode but have been unsuccesfull. I will check your suggestion and let you know.

Hi Keanone, I have checked your suggestion.
You can define a speaker group in the Advanced Settings of the RADIO channel.
All other channels (TV, HDMI, etc) do NOT have a speaker group setting.
