how transmit raw audio from ROKU via HDMI to TV so soundbar can handle it?

Roku 4662X HDMI to Vizio V436-G1 4KTV connected:

Roku HDMI to Vizio M21d-H8R soundbar HDMI to TV HDMI1(arc)

Does not show anything other than stereo PCM to TV.

Roku Audio Mode = auto, Roku Audio HDMI = DD+, DTS

But any setting I try and the TV only sees stereo PCM. No volume modes set. (*)

The reason I ask is because Samsung K8500 4KBRplayer (when I changed settings to output raw audio)(connected to HDMI2), TV now sees DD etc etc.

How can I get Roku to do that. Tried all roku settings. tried all tv settings. long chat twice with Vizio.

All I get is 4K and stereo.

How to do that with Roku?

Thanks!!!

 

From roku's specs:Audio features
Digital stereo over HDMI®
DTS Digital Surround™ pass through over HDMI
Supports pass-through of Dolby-encoded audio over HDMI

still no answer on this. So using TV's Smartcast mostly but Roku is simply easier so would love to get it going with DD. Thanks!
