Over two months since I opened this... Still have not had any official response from @GraceFromGoogle @ChrisFromGoogle. It's going to be a real PR disaster when Stadia is launched and you get people paying $10/month for premium and not getting what they are paying for because google can't support Dolby.
same with me here, i only get Stereo on my Sony 91 Headphones... It has separat LEDs for Stereo or Multi Channel input ..... On other apps Inputs it works fine, it only wont work with Stadia. I am using a high end lg oled, sony 9.1 Headphones and a Chromecast on wifi.
There is 5.1 sound on CCU. However you have to have a receiver that supports Lpcm. If your Chromecast is connected to your TV both your TV and receiver have to have eArc in order to get 5.1 surround sound. For some reason they don't use Dolby
I just tested on the computer and if I have 5.1 and it works well, but in the CCU it doesn't ... We are in the same if the TV or the amplifier does not accept LPCM we don't have 5.1, it would be solved quickly if they put dolby audio but Google doesn't want to pay license in the same style as Nintendo swich
Yep... I'm in the boat where I have a 4K but my receiver doesn't have eARC so no 5.1 for me. If I plug into my receiver, I get 5.1 but no 4K. It's unfortunate to have to pick between one or the other. I can spend $$$ on a new receiver but at this point literally the only thing in my set-up that doesn't get 5.1 is Stadia. I get 5.1 with Netflix on my CCU... but not stadia. I can't see me spending $$$ on a new receiver when the whole point of stadia was to not drop $500.
