Fair enough. Sling doesn´t output audio to the Homepods using the old method, and neither do video games. I suppose its app dependant. Just one thing. By "the option we have now to connect to airplay everytime" do you refer to long press the Home Button on the ATV, and then select the Airplay menu on the control center?.Whether you agree with the finer details is really neither here nor there. With the 14.2 upgrade there has still been a down grade of functionality to the 4th gen HD only models, as they have removed the 'Audio Output' option and there is nothing to replace it.
The 'audio output' method although not perfect was better than the option we have now of connecting to airplay everytime we want to use the apple tv, which my 4yr old cannot manage on her own, (which incidentally also does not include system clicks and I never had any issues with the old method with IPTV, I use channels and iPlayTV)
It used to be possible to long press the play/pause button on the siri remote to bring up the airplay audio menu directly, right?. Thats also gone?
