IMO the BEST feature of the Apple TV is the Wireless Audio Sync in the Audio settings. I have my Apple TV setup to synchronize all Music, Movies, and TV shows throughout each of my Apple devices.
- Living Room TV with my Samsung Soundbar
- Bedroom M1 MacBook Air with an external AU and 2X KRK R5’s
- Restroom HomePod Mini
And I can also control everything from my iPhone of course!
Unfortunately no, my Samsung Soundbar is connected to my AppleTV.
