I have the arc with a sub and 2 sonos one’s. I use an apple 4K tv and the Optoma UHD60 projector.
The UHD60 has an S/PDIF (optical) audio out port that offers Two Channel PCM (Pulse-Code Modulation).
What option will give me the best surround sound experience? (And better yet, are any of these inferior?)
- Wireless Connection using the Apple TV settings ‘video and audio’ > ‘audio output’ (easiest)
- Hdmi from the arc to the optical out on the Optoma (using the hdmi/optical adaptor supplies by Sonos)
- Purchase a receiver that has hdmi arc audio output capabilities (would love a recommendation for a good and simple receiver just for the Apple TV input with the hdmi arc audio out and a 4K hdmi out)
