Sonos beam with 2 Play 1s Surround Issue

I just got a TCL R625 which I am using with a Sonos Beam (Hooked up via Arc HDMI) and two Sonos Play 1s. The Roku software is updated to 9.2.2 build 6106-88. I can get surround from every TV app (Amazon, Disney, Apple TV, Vudu) except for Netflix which appears to be playing back in stereo? The TV is set to autodetect the audio source but I have tried auto passthrough, dolby digital etc and no change. 

What is odd is I have this exact Sonos surround setup on the older TCL R615 and it plays surround in Netflix just fine.

Every device is up to date (Sonos even says Dolby 5.1 signal while the Netflix stream is playing). I have noticed the surround going to my xbox seems to work off and on as well which is odd. It also shows Dolby 5.1 in the sonos app while playing.

    I’ve never known a TV to do any conversion of audio codecs, but that may be something you want to pursue with TCL. I’m not that familiar with the brand, or the apps they’ve built in. 

    Perhaps you are correct? But I've read several places that Netflix uses DD+ which Sonos will not play. Yet on my other identical Sonos setup it does indeed play the same Netflix Roku app (different TCL model though) so something is doing the downgrade or is communicating that the sonos needs something less than DD+ to play.  Stating all that, I certainly concede my lack of knowledge as to how this all works. Haha

      I would appreciate any help in your resolution to this issue. Have exact same problem. Very frustrating. Spoke with Netflix...nothing. Every other app and cable fine with surround. Thx!!!

      I would gladly provide any help if I myself receive a resolution to this issue which thus far I have not unfortunately.

      @Jawbox I have the TCL55 Roku Tv, and I don’t have this issue.  Try going into audio settings, and deselect “Auto”.   Set your audio settings to “Dolby Digital”.  All apps should then send only a Dolby Digital signal.  Autodetect will always send the highest signal possible, which on my TCL with Netflix, will always be Dolby Digital +.

      Hope this helps.

      Thanks for the reply but I have already tried all of the above to no avail (Dolby Digital). And just to be clear, you're talking about the R625 TCL 55 inch right because that is the only model I am referring to. It works fine on an older TCL R615 55 inch TV I have.  Cheers

      I’m not entirely sure which exact model I have, I’ll check when back home.  I just know that when I used autodetect, my Sonos didn’t work, because Netflix was sending DD+.  When I specifically set the tv’s audio settings to DD, I no longer had Netflix issues.

      Yeah my older R615 model the autodetect actually works fine with Netflix. So I had that setting on the newer R625 and it did not work (as you've described) so I walked through all the settings including DD and it still only plays stereo for Netflix. Seems like a bug. The Sonos app actually does show Dolby 5.1 as being played, just no sound from rear speakers, only hissing. Pick another app though and the rears work fine. Odd
