This should work if you enable ARC (must be enabled on Apple TV settings, and on your HDMI switching device. You also need to use an ARC compatible HDMI cable and to be using the ARC port on your "switching" device, since often there is only one such port. This is how I have it set up and my HomePod outputs all inputs that come into my TV.

My Sony Bravia TV auto-detects ARC and will pass it to my Sonos. I didn’t have to change my Apple TV settings.

When it works - it’s magical. You can turn tv on/off.

Except sometimes volume control goes haywire and only one side adjusts.

Then there’s weird stuff like asking “play the beatles” responds “I couldn’t find Beatles in your library” even when you got music subscription.

Overall biggest pain point is same as all apples - debugging

I’ve used ARC with a stereo pair via my Apple TV for a while now. It sounds amazing. I can even play FPS games on my gaming PC with the audio piped to my HomePods, through the Apple TV via ARC, and there is no noticeable latency.

Therefore this also means I will have to buy another Apple TV, only the 4k 2nd gen supports ARC. I see no reason to do that :-( it works just fine the original 4K one. Thx!
