There’s been a lot of confusion on this forum (and others) about Atmos compatibility for the Sonos Arc with non-eARC TVs, especially where the Apple TV is concerned.
I have a 2018 Vizio E-Series and after reading entirely too much information on the subject, I still have absolutely no idea if I’ll be able to get Atmos sound from my Apple TV 4K through the Sonos Arc. Seems like a 50/50 chance at best.
I’ve just pre-ordered an Arc and should receive it by the end of the week. I’ll test Atmos compatibility through my E70-F3 via both Apple TV 4K and the built-in apps. In hopes that it will help other E-Series owners, I’ll post my findings here. And if I’m able to get Atmos one way but not another (I’m assuming that if anything works, it will be the built-in apps), I’ll post my (extremely subjective) thoughts on Atmos vs. Dolby Digital Plus sound quality
For what it’s worth, if anyone has any questions or anything they’d like to know, just ask - I’m happy to test as much possible to help answer compatibility questions.
FYI, thanks, and fingers crossed for some Atmos!
