Add me to the list of people where 5.1 is not working. I have the CC ultra plugged in to an HDMI switcher with digital optical output. I need this for my old but still good soundbar. Other systems - PS4Pro, XBox One X both output bitstream 5.1 great. I can get 5.1 to output from the CC when playing Google Play movies no problem. Netflix or Stadia are only 2.0.
Hope this gets fixed soon, I otherwise love Stadia. This will keep me from using it though for new releases.
I have this issue but not constantly.
I have the CC connected to my Onkyo receiver which is connected to my LG B8 TV.
I can detect the input stream from the chromecast through the on-screen display of my receiver.
I've noticed that sometimes, when starting a new session of Stadia and then starting a new game, I will get a 2.0 PCM stream even though my connection is Excellent and shows 4K 5.1.
I can cast Netflix at those instances and receive a 5.1 input stream on my receiver.
Shutting down and restarting Stadia doesn't solve it BUT the solution which works every time is REBOOTING the chromecast through its settings in the Google Home app on my phone. That solves the problem for me but of course it is very annoying as it seems like every other session I have to restart the chromecast in order to receive a proper 5.1 PCM input stream.
Same issue here. Stadia support say it's my TV at fault, my 2019, 4K TV Dolby with Atmos and every other feature you could imagine. However, every other 5.1 surround source such as xbox one and firetv works fine (passes 5.1 surround to av receiver)plugged onto same hdmi that the chromecast used.
Yes, very frustrating. This is literally one of the top issues on this community forum, yet NOBODY from Google has responded or given an update. They want us to pay for pro, but instead of getting what they promise, we get upscaled 4k and stereo sound. Man, makes me really want to stay subscribed. @GraceFromGoogle @ChrisFromGoogle
Same issue here. I'm connected to my TV with a digital optical cable and my TV does support native app 5.1 support for apps like Netflix with no problem. With the Chromecast and stadia the sound is only simulated with Dolby Pro Logic II meaning that it's getting a stereo signal and not the true 5.1...stadia does not support Dolby surround at this point due to not having a license? The Teufel Concept E Digital Im using doesn't have an HDMI input so I can only use the optical digital cable and there's no plugging in the Chromecast directly.
I hope they add Dolby surround sound soon. At launch they said 5.1 support and just supporting the free non licensed codec of lpcm/pcm is not cool, Google. At least allow Bitstream like other consoles do - my TV should be able to handle that since there's an option for it as well.
