Hope you can help with the question below.
Situation: I’m thinking to buy the Sonos Arc. I am thinking to use it in the following structure: Connect my Apple TV 4K to my project BenQ projector via an HDMI cable for video output, and stream the audio via Airplay2 to the Sonos Arc. (Note: My projector does not have an earc, so am hoping the Airplay2 will suffice for audio output)
(1) Will this above set-up work and, if so, will there be any audio lag/discrepancy with the visual?
(2) How big a difference will the sound quality be in using AirPlay2 for audio output rather than HDMI earc. I read that Dolby Atmos only works with the cable through the arc.
