No audio when selecting Sonos Move speakers on Apple TV 4K

Hi —

I see my Sonos Move speakers as available for audio when I press the TV button on my Apple remote. However, when I select the speakers I lose all sound. When I do this the speakers are on their WiFi setting. I am able to connect to a Bose bluetooth speaker, however I would prefer to link with the Sonos Move speakers via WiFi.

How can I achieve this?

Best,

Cindy
