Dolby Atmos NOT working with the Chromecast with Google tv !!!

Soxbrother

Hello,

 

I have the New Chromecast with Google tv since last week.

I bought it especially to have Dolby Atmos with the streaming apps.

I'm sad to say that Dolby Atmos isn't working at all !!!

I've tried Netflix and Apple TV +, so far.

My setup is as follows :

Chromecast --> Samsung HW-K950 soundbar --> Samsung UEJS9000 tv

So it's directly connected to my soundbar, so Dolby Atmos should work.

Sound settings were on automatic setting, but when I go inside the settings and choose the manual sound setting, Dolby Atymos is enabled, as is Dolby and Dolby Digital plus.

When I disable the surround sound toggle, I get sound, but not Dolby Atmos.

When inside Netflix the Atmos logo displays on screen, but there's no sound.

The same goes for Apple Tv+.

And no, it's not a soundbar issue, but a Netflix, Apple tv+ or Chromecast issue !!

Because for example when I play Netflix on my Windows 10 pc, that's connected directly

to the soundbar, it does play Dolby Atmos.

 

When will this problem get fixed ?

 

Thanks in advance.

Greetings,

Soxbrother

As I suspected, but, I had no idea what your TV's capabilities are.

It seems odd that you would expect it to work though. If the TV needs HDMI ARC, and the only thing with ARC is the speaker reason holds you're missing a few ports necessary for the signal processing for ATMOS to be completed. Buying an ATMOS speaker and expecting the CCwGTV to complete the cycle on a TV that doesn't support the enhanced sound isn't going to work. Your speaker can't send the enhanced digital sound back to the TV for processing so that it can be looped back to the speaker. Why? Because your TV doesn't support ARC. Besides, the CCwGTV carries the stream to the TV expecting the TV to process what's been sent so that it can then send it out to the speaker with the proper sound effect signals. So, in short, CCwGTV is designed to be connected directly to the television's HDMI port. CCwGTV supports receipt and delivery of ATMOS coded theatrical/TV file streams for processing downstream by the TV that then sends the proper signal to the speaker.

Samsung UEJS9000 TV specifications doesn't seems to list eARC support, so no full Dolby Atmos, Dolby Digital HD or DTS Master Audio sound.

However if you are watching Netflix streams with Dolby Atmos soundtracks your TV ARC enabled HDMI port should be able to handle Dolby Atmos embedded into DD Plus stream.

Furthermore ensure to have Anynet and digital audio passtrough enabled on your TV. On GCGTV side check in sound settings to have allow multichannel sound enabled.

Hi @Soxbrother if it works with your computer sending directly from your computer to the soundbar, it would reason that if the CCwGTV is connected to your TV instead of the soundbar, the same might hold true. Have you tried that?

Hi, that would work, only if your tv has an hdmi E-ARC. Because only hdmi E-ARC supports Dolby Atmos through hdmi.

So no point in trying that, because my one connect box doesn't have hdmi E-ARC.

That's weird, that the chromecast would need the tv to send the Atmos signal back to the speaker.

The chromecast is directly connected to the speaker, why would the sound go to the tv first and then to the speaker ? Makes no sence.

 

That would be the same as if you say, that if you play a 4k ubd disc with the Samsung ubd player, that it can only play the Atmos audio if the player is connected to the tv first.

Only if you have e-arc, then such a connection would work, that's in fact the only way such a connection can work for Atmos audio.

The tv is a separate thing. For example, I could turn it completely off and the sound would still be playing from the speakers, because of the direct connection.

And it's also not a question if the soundbar supports dolby digital plus with Atmos, because it plays it fine from other sources.

If the chromecast really didn't support Atmos and digital plus on my setup, then it would say so, just like it says in the setup menu that AAC sound isn't supported.

So in conclusion :

Atmos should work if :

- chromecast to soundbar hdmi input, then soundbar hdmi output to tv

Or if you have one the more recent tv's :

- chromecast to tv e-arc hdmi and e-arc output to soundbar

I have no further suggestions or explanations; it doesn't work even though you think it should; it's not a failure of the CCwGTV. If you decide to connect it to the HDMI port on your TV and have issues let us know. Maybe you should try reaching out to the speaker manufacturer.

Your TV set have 4 HDMI ports, but only one of them has ARC functionality. Connect the soundbar HDMI ARC output to the HDMI ARC enabled input of your TV.

It's connected that way already.

And the chromecast is connected to hdmi input 1 of the soundbar.

The only thing I can try is to connect it to input 2, but that's not going to work either.

Indeed, but the chromecast is directly connected to the soundbar, bypassing the tv. Like the Samsung UBD k8500 player is also connected, directly to the soundbar.

 

I will try the chromecast in my one connect box, but this shouldn't give me Atmos, but I will try it.

So I've connected the chromecast to the one connect box of my Samsung tv, and as expected the Dolby Atmos audio didn't work.

Furthermore, in the chromecast settings, when you choose manual audio settings, dolby digital plus and dolby digital plus with Atmos, are now in the "not supported" section. Were as before, with a direct connection to the soundbar, ony AAC wasn't supported.

If my system really wasn't able to handle it, then it should say so, just like it says now, when connected to my one connect box.

Hey there Soxbrother,

 

I'm sorry about the slow response time on this, but an eARC soundbar is backwards compatible - if the TV does not support eARC, it falls back to regular ARC. Just to confirm what both GothamNY and djtetei were saying, I'm sorry to say, but your setup is not compatible to output Dolby Atmos since your TV does not support eARC. Connecting the Chromecast with Google TV to the soundbar does not bypass his compatibility.

 

Based on experience as well, for bandwidth heavy media formats, you'd really need a setup that is compatible to eARC. This also happens with Stadia users, which is why it is a requirement for surround sound in general.

 

I hope this helps you out, and if you had any other questions or concerns, please let me know.

 

Best regards,

Jeran

It's not bypassing the TV. The audio and video signal is still being sent to the TV by the HDMI ARC output of your soundbar.

Yes I know, but I actually meant the Dolby Atmos audio.

You need to enable it on the TV Anynet CEC interface, because your soundbar doesn't have a display where you could make the proper settings.
