Chromecast with Google TV: no Dolby Digital 5.1 surround

I am not getting any surround sound from my new Chromecast with Google TV (CCGTV).

Its plugged in a Samsung TV. Sonos Beam connected via HDMI ARC.

The CCGTV audio settings are set to Auto: Dolby Digital or Manual: Dolby Digital (tried both)
The Samsung TV audio settings are Bitstream - PCM (Dolby Digital and DTS greyed out, not available)
My TV is playing stereo 2.0 PCM only.
The Sonos app only shows stereo 2.0 PCM. 

 

My PS4 is in another HDMI input, set to Bitstream-Dolby Digital.
The Samsung TV audio settings are Bitstream - Dolby (here Dolby is available)
My Sonos is receving a Dolby 5.1 signal, the Sonos app shows Dolby Digital 5.1 from the PS4.

So the TV can passthrough Dolby 5.1. 

Is the CCGTV not outputting the right format?
Can someone assist me to find a solution?

The fact that Dolby Digital is greyed out on the TV’s options page indicates that one end of that cable thinks this is not possible. As the other HDMI port is happy with DD5.1, looks like the CCGTV is the problematic end of the cable: it is not satisfying the DD5.1 handshake either because it cannot, or the source signal doesn’t contain DD5.1 content.

I’m having the same issue. 5.1 works fine from other inputs but only 2.0 from CCGTV.

    Thank you for your response. I went back to check.
    As you can see below. The Chromecast states correctly that only DD is supported and is selected.
    The source apps Netflix and Disney+ support 5.1 content as far is I know.
    The TV only shows PCM or DTS Neo.

    I am at a loss to get this working.

    Same problem here. I also have the Sonos Beam in combination with a sub and two ones, I

    just tried the Amazon Video App where Surround Audio is working!

    Maybe the Disney Plus and the Netflix App does not support Dolby Digital on the new Chromecast? Is there maybe a way to make this working?

    I just activated the Dolby Atmos function and surprisingly 5.1 Sound is working in Netflix on all 5.1 content. But as soon Dolby Atmos is available Netflix is not playing the video (as the Beam does not support Atmos I guess).

    Seems like a workaround for all 5.1 content where Atmos is not available. Hopefully Netflix will release a fix soon.

    @MagnusST Are you talking about the apps on your TV or via Chromecast? On my old TV I could never get surround to work from the Chromecast (not using it on the new TV).

      @MagnusST  Thanks for the suggestion, but for me it did not work. Stereo PCM in all scenario's and apps. I returned the Chromecast. Maybe I will try a Mi Box S.

      I use an Nvidia Shield. Works great. Only thing is the Prime app does not do DD. I use my TV for apps though.

      Well, I have two TVs, the Samsung and TCL. When I connected the Chromecast with Google TV to the Samsung, I got the same result as the OP. Just switched the Chromecast to TCL and got 5.1 DD+ and Atmos passing to Sonos Arc.
