Hi there,

I have an Apple TV HD (2021) that is connected to my Optoma HD146X projector via HDMI. I want to play video through the Apple TV, but would like to play the audio through my Sonos setup (a Sonos Five and a Sonos One). When i play video through the Apple TV, the sound comes from the beamer built-in speaker through the HDMI cable. 

I can't figure out where/how to connect the Apple TV to the Sonos for the audio playback. 

What does work, however, is to go to the Netflix app, and from there scroll down on the Apple TV remote and select the Sonos speakers for playback. If i then switch to any other app, these audio playback settings are carried over to this app, and audio is played through the Sonos speakers. If i then want to change volume, i have to go back to the Netflix app as that seems to be the only place where i can control the audio sound settings for Sonos.

Does anyone have an idea what i'm doing wrong and how i can fix this?

Thanks in advance!
David
