Apple TV 4K could not set a Single Homepod Mini as default speaker.
My iPhone is running at iOS 14.4.1, My Apple TV 4K is running at 14.4, same as my Homepod Mini.
I can manually set Homepod Mini as the Apple TV's speaker by setting in Apple TV's control panel.
I can not set Homepod Mini as the Apple TV's default speaker in TV's setting menu.
Both of my 3 devices were in the same Wi-Fi network. The TV and Homepod Mini is in the same room.
Thanks for take a look and help me out.
HomePod mini, 14
