Dolby Vision + HDMI CEC issues for ASA

Hi o all to be honest is not impossible to do Dolby Vision on all the Xboxone and the reason is very simple. The real benefit of Dolby Vision is that it doesn't need the new HDMI 2.0 standard to work. 'Regular' HDR10 signals do need
HDMI 2.0, a standard that only the latest kit has. Because Dolby Vision can operate with HDMI 1.4, its potential applications are much greater, which is very good news. http://www.pocket-lint.com/news/140385-dolby-vision-is-now-available-as-a-software-update-to-upgrade-compatible-kit

Of course the Blu-Ray disks I'm using are UHD and have Dolby Vision.

Dolby Vision is enabled on Xbox One X settings, TV HDMI ports are in Enhanced mode (4:4:4 4K/UHD HDR 60Hz), and the TV test (that can be found inside Xbox menu) returns all green ticks for my Xbox-to-TV connection.

As said, Dolby Vision works with all streaming apps... but not when playing Blu-Ray UHD Dolby Vision disks.

The HDMI 2.0 won't affect the Dolby vision, right?

Can I still use the HDMI 2.1 in my TV or do I need to use the old 2.0 HDMI?

Here’s my tv specs

Active HDR10 and Dolby Vision. Using brand new premier hdmi cables from monoprice that support hdmi2.0 specs, which include 4K60 and both dolby vision and hdr

Update, I disabled eARC and HDMI ON to OFF on the Denon receiver. And on the TV, I also disabled eARC. On the Xbox series X I disabled CEC and ever since then I haven't had an issue with the audio. I did notice when I enabled CEC on the Xbox, and choosing Dolby Atmos I lost audio intermittently, so I just left CEC off. Unfortunately I have to use 3 controllers to turn everything on now. Now I can choose different audio formats with no audio loss.
