Also cannot make this work, similar setup to jimbsparks, including same TV model, and a Denon A/V unit. If my collection is on Vudu, this nullifies my audio setup. Very frustrating. If it works with other apps/channels, feels like it's just laziness to leave it broken.
shwanyboy,the solution that worked for me was to get the latest 4k Roku stick and plug it into the Denon. That way the audio hits the Denon directly. Vudu now plays Dolby atmos sound with no problem. I gave up on trying to get the tv to push the atmos track but will not work, I am a firm believer that it is both a firmware and an app issue on the tv. Both TCL and Vudu and Roku just do not care to even research it the issue.
