Getting Dolby Atmos to work on Xfinity Flex
Per this article: https://www.xfinity.com/support/articles/dolby-atmos-x1 I understand that X1 provides Dolby Atmos content. I have an Xi6-T Xfinity Flex box and I am unable to find any Dolby Atmos content (via voice search for "Dolby Atmos"). I've called support and received varying answers on whether or not Flex supports Dolby Atmos (yes it does, no it doesn't, I am not sure).
Can anyone here with an Xfinity Flex box confirm whether or not they can access Dolby Atmos content?
My current set up: HDMI 2.0 cable running from the Flex to my Dolby Atmos sound bar. Another HDMI 2.0 cable running from the soundbar to my TV's ARC port. ARC/CEC on my TV are working fine and Digital Audio output is set to bittstream. Video and audio are also working fine, I just can't get/find Dolby Atmos content (just Dolby Digital, etc).
Lastly, can someone please DM me the instructions for doing a factory reset on my Xi6-T box?
