Wanted to purchase the full package (unfortunately out of stock right now) with the Arc, Sub G3 and 2x One SL but I have an issue.
 
My TV does not support eARC which means I cannot experience TrueHD Dolby Atmos. I saw that there is an Optical to HDMI adapter included with the Arc.
 
Does this mean that I CAN experience TrueHD Dolby Atmos using this connector and not having a hassle with two remotes?

No, TOSLINK (optical) does not have the bandwidth for Atmos. You can use Arcana to play Atmos from an external box, but not from a TV App. I can’t promise that Arcana will solve the two remote issue, but you might get lucky.

However, normal HDMI ARC does have the bandwidth for Dolby Digital Plus, which does carry a version of Atmos, as well as using CEC to carry the remote’s commands.

Thanks for both replies, Buzz and Airgetlam. I am using these apps on my TV as well as a TV receiver from the TV company: Netflix, Prime, Youtube, Spotify. Do these apps support DD+ and Dolby Atmos? Feel kinda ripped off by Samsung giving me false promises regarding eARC suport on my TV.

Im already helped with my issue/question using a different tech-platform :)

- Optical does not support Atmos TrueHD
- The HDMI ARC connection works fine with my Sonos setup
- The streaming services I use do not support Atmos TrueHD
- These do support DD+ whatever the ARC connection supports.
- I can use a HDFury Arcana in the future for Atmos TrueHD.

As far as that goes, I don't have to worry about the problems that the combination of TV and soundbar could cause. Moreover, I can use the HDMI cable and there is no fuss.
