Having issues with 5.1 surround sound

On other apps connected to my TV I'm able to use eArc and output Dolby Digital surround sound on my receiver. If I cast to my Chromecast I'm able to get it to output Dolby Digital. However when playing a stadia game on my Chromecast, it only outputs stereo. I have gigabit internet, but in the connection tab, I'm only seeing 4k & HDR. There is no icon for 5.1. Do I need to enable this somewhere? Plugging into my receiver yields the same results. Stereo only.

Glad you found a solution. Unfortunately I'm in the US and it doesnt look like there is anything comparable... most of the ones sold here are 4k 30fps max. It would just be so much easier if google didnt go the cheap route and implemented 5.1 surround that most people are going to be able to use.

I have a very old Receiver Yamaha HTR-3063 and get 5.1 sound. Just plug in Chromecast Ultra in HDMI 1 with PCM suppprt. Set receiver to PCM and 5.1 works perfect. Only thing is, that I have no 4k then, just 1080p

If it helps, Ive been onto Stadia chat today. I had the same issues when my Stadia arrived today, having used it on a 100mb connection but solved it by plugging into my receiver rather than the TV. I think the issue is that while you might have ARC/passthrough/ 4K TV and receiver, Stadia relies on having eARC which is a new higher bandwidth ARC port which a lot of TV and receivers dont have. So my TV which was new last year (Samsung) was outputting in PCM not dolby digital (the PS4 works fine as is DD) but the receiver can cope as it doesn't rely on pass though via the TV.

So it's a pain, but if you otherwise have a modern set up it should work.

The trouble is, you then also need a receiver that handles 4k or at least does 4k pass through. Mine is a high end 9.2 receiver that I had no intention of upgrading at the cost of several thousand just because Google won't use something other than PCM or provide a backward compatibility.

At present I have a TV that I paid money for to handle 4k and HDR, and a sound system that can handle the best sound there is. But because you must plug stadia in to one or the other then you are stuck if you haven't got eARC on both! Bloody stupid.

Fact is, PCM is licence free and Stadia would have had to pay for Dolby digital (I think). And when you look at the history of Google and Android, they have always tried to use licence free stuff even at the expense of user experience.

The best solution I have found is to plug Chromecast Ultra into a device that splits the 4k and PCM stream into two separate. One then goes to TV and other to receiver and for a much more modest cost then new TV and receiver. Trade off is HDR not available. See my previous post here with Amazon link:

Yep. That's exactly the problem. Most people don't have state of the art TV's and receivers. Most people already have a completely good system that works with everything else in their system. The whole point of stadia is that you don't need to buy anything. But in order to play in 4k on your chromecast you have to have a TV that supports 4kHDR and eARC and also have a receiver that supports 4K HDR and eARC. I can guarantee you the majority of the people that are on stadia do not have these or come anywhere close. What get's me is that I started this thread almost 6 months ago. Still no official comment in here from google. Lot's of other threads have had google responses but they just seem to ignore this one.

Hi Makaveli, my amp is a Yamaha HTR 3069 which is their entry level one. Perhaps I'm just lucky that it appears to work and HDR does work. Destiny 2 was quite impressive and the wireless connection says excellent so it seems to say the right things on screen. I also have a high speed HDMI cable which can deal with 4K, sounds like we are all as up on this as each other so we understand how these things should be plugged in. I have to say though that it failed once on 5.1 after working properly and I wondered if getting the right broadband connection when switching on isn't entirely stable, despite speed which was still shown as excellent. I do think Google need to change the setup instructions though as clearly plugging into TV isn't always the solution.

I am also a new samsung TV user of the year 2019 and I have the exact same problem, but neither the 2020 samsung televisions are compatible with eARC, samsung does not use this standard of audio or video transmission, there are many complaints, why Samsung 8k TV was purchased and does not have eARC. I really do not know which brand of Televisions uses or allows this transmission standard.

Sad day for me today, returning my stadia. Hope this problem will be resolved in the future.

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.

My words.... We are not casuals, we are nerds, gamers and techies. If they hit casuals with this lack of promised 5.1 Sound, they will **bleep** it all up. Besides: I know why I can't have 5.1 Sound when CCU is connected to my TV, as I have a 2019 LG with HDMI2.1 but obviously they have not all eARC features fixed yet. So the Signal from CCU can't (yet) be forwarded to my reciever. Update WILL come 2020, but as my TV is on the upper end of technology, I doubt that most of the TVs out there are able to do so, too. Connected to my receiver 5.1 works like a charm, but I don't want this solution. CCU should be connected to the TV. At least as long as my TV recognize the CCU as CCU. 😉 Fun fact: My LG does not know what the CCU is. It does not recognize it. My ex wife's Samsung does recognize it imediatelly. That is why I can't plug it into my receiver, as without recognition it won't switch to the right input channel.

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.

I'm having the same problem, no 5.1 Surround Sound output. I have Sony X900E using ARC to my Onkyo Reciever. I have Dolby Digital Plus Bitsream enabled on my TV, and no so surround output.

Hi,

any news on it? It it's really disappointing when a feature we have paid for is not working at all.

Is 5.1 surround sound with Chromecast working for anybody here?

Best regards

Streaming literally anything else on my Chromecast I can get 5.1. With stadia I'm out of luck... They don't want to address it either.

You have to plug you ChromeCast into your receiver. Even though my TV supports eARC (as it has HDMI2.1 already) and my Receiver does, too, I can't get 5.1 sound when plugged into my TV. When I plugged it into my receiver, it worked. So YES, it IS a problem on Stadia side. But NO, you won't get - for now - 5.1 if plugged into a TV.

Google support told me it will only work if plugged directly into TV. They also told me they had not heard of any one else having the issue!

That would make sense if we weren't reciving 5.1 surround sound codecs via other apps on the Chromecast Ultra. It's merely a Stadia application error.

Same thing here. Stadia only seems to support Linear PCM 5.1, which works on my receiver when directly plugged into one of its HDMI ports (and a factory reset of the chromecast), but not when plugged into the TV using ARC.

My receiver doesn't support 4K/60 passthrough nor HDR, so I'm stuck having to choose between 4K+HDR or 5.1 surround until Stadia supports sending our DD+ 5.1 which is supported through ARC.

Given that the audio also has a serious sync issue, I'll stick with 4K+HDR and headphones for now. 😢

Sometimes Stadia seems to kick off the Chromecast in stereo for me (plugged directly into my amp). If this happens I've so far fixed it be casting something from Netflix in 5.1 then stop casting Netflix and start Stadia again I get 5.1 from Stadia

Been on with customer support twice now. First time they said they said it was connection, and maybe just plug into amp, and basically all the stuff some says when they have no idea. They said they would "escalate to higher ups" and I'd get a call back that evening. Got nothing.

Second call, the guy said it was game specific and you have to switch it on from within the game. He was then stuck because there was no option in any in game menus.

Now waiting again for a call back which probably won't come.

I did tell them about the many people here with the issue who are getting no assistance and ultimately I would like to make a formal complaint. He told me there was no way to do that unless I wrote a postal letter to Mountain View.

So, great service all round.

Same problem, I've got the first edition I plug directly on my amp Pioneer lx 701 the sound is on 2.0. Like someone else said, I cast a Netflix movie 5.1, get back on Stadia the sound appear on MultiPCM 5.1

But if I reboot Stadia and my amp, the sound come back on stereo every time..

This is strange because at the first time with Stadia the sound was directly on 5.1
