I do not believe the Roku Express devices can output Dolby Atmos. They are able to do 4K video, but not Atmos audio.
From the Roku web page, it states this:
-
Digital stereo over HDMI®
-
DTS Digital Surround™ pass through over HDMI
-
Supports pass-through of Dolby-encoded audio over HDMI
Correction: I have the standard 4K stick, which should output Atmos. Sorry for the confusion.
You may want to reach out in the Roku forums, or contact Roku’s CS, since the Sonos itself seems to work.
Make sure the TV is set to these settings:
HDMI Input Audio Format: Bitstream
Digital Sound Output: Pass Through
eARC Support: On
Yup, I did that, but I still only get stereo sound.

Be sure the Digital Output Format setting on the Roku is set to Passthrough. Set the Preferred Streaming Format to Dolby too.

So you do no even get 5.1?
