Just wondering.some people have been told that this is a cosmetic error, that the signal is in fact Atmos but somehow it's showing as Multi Channel In on the receiver.

Try contacting DENON, but it really does seem like an XBOX vs application problem. If anyone has a fix, I would greatly appreciate it! It looks like people have being having difficulties with all this for some time. Understand why it can stream media correctly for audio or dolby vision. My Apple TV 4K only pulls dolby vision for content that has it. On the other hand, Dolby Atmos headphones are designed specifically to work with Dolby Atmos. So, if you’re using a decent pair of regular headphones, as long as it’s properly connected and set up on the app, you should still get Atmos sound quality. I am using MS Edge which is supposed to support 4K/UHD I just want to test the system to make sure it will actually run 4K / UHD content. We do not have the upgrade UHD Netflix and I only mentioned it in case someone has settings to share. On another note, I've noticed DOLBY VISION seems to always be on for NETFLIX despite some content not being DOLBY VISION. Keep in mind, the key to enjoying Dolby Atmos on any headphones is the Dolby Access app, which pretty much does most of the work. VUDU has disabled PC 4K/UHD to work on some issues. It seems to pull ATMOS from streaming VUDU, NETFLIX, DISNEY+ correctly. Me easier, is my APPLE TV 4K works with my receiver correctly. Other popular services include Vudu, which streams 4K UHD movies. I just purchased a DENON x3600 receiver for ATMOS and am very frustrated. Microsoft is not compatible with Dolby Atmos technology, so its new Atmos-certified. Turning my sound settings off and turning them back in to no avail. I tried deleting the ATMOS app and reinstalling it. It seems like it is likely a combo NETFLIX and XBOX problem and

The Xbox One X does pick up ATMOS from 4k UHD discs that support it, but apps like Netflix fail to properly stream ATMOS. I am also having difficulty getting Dolby ATOMS to work properly.

Does tubedigger work with vudu
