The thing sounds good in stereo, but I've tried playing Atmos content and all it says is TV ARC. First thing I tried was to plug my Roku Ultra LT into the HDMI input of my soundbar, with the ARC connected to my Sony Bravia's ARC, which I checked and saw was set for enhanced. No Atmos from any provider. I tried Amazon Prime's Lord of the Rings series. HDR worked, but the Soundbar never said Dolby Atmos. Then I tried using Prime from the TV's Android app. No Atmos.
Then I plugged the HDMI into the Bravia, making sure that the input was set to Enhanced ARC. Repeated playing Atmos content, no Atmos from Roku or built in apps.
I can understand your frustration with setting up the Atmos with your soundbar. It can be tricky at times and can often be difficult to enable if even one device is not compatible with the feature. You stated you have Bitsreaming enabled. Do you also have "no encoding" selected as well? Open the audio output options on the settings menu of your device and make sure that “No Encoding” is selected for Bitstream. For example, on a Samsung BD Player, go to Home Menu → Sound → Digital Output and then select Bitstream (unprocessed). Let us know if this helps.
