No sound output from homepod when connecting to Apple TV 4k under Youtube App.
The combination of Apple TV/ HomePod/ Youtube can work properly at first setup. And I try other APP like Netflix can work properly, sound can output from HomePod.
After Apple TV sleep and wake up, the device linking is still connected from Apple TV to HomePod by airplay. But when I launch Youtube, the sound cannot be heard by HomePod. At the same time, I launch Netflix, the sound can be heard by HomePod.
In order to solve this problem, I have to reboot Apple TV. And the device linking will change to Apple TV/ TV(HDMI). After changing the device linking to Apple TV/ HomePod, the sound can be heard by HomePod under Youtube.
I need to do these steps when I want to watch Youtube, this situation is very troublesome.
