Question Setting up Dolby Atmos Audio Configuration with NVIDIA RTX 4070 on Windows 10

[pierred512]

Hello everyone,

I have an NVIDIA RTX 4070 graphics card with multiple outputs, including several DisplayPort ports and an HDMI 2.1 output. I'm using Windows 10 as my operating system.
I would like to use one of the DisplayPort ports to connect my 4K monitor for gaming visuals, and reserve the HDMI 2.1 output exclusively to connect my Dolby Atmos soundbar for spatialized audio.

Is it possible to configure this setup on my PC?

Additionally, could you confirm if using Dolby Atmos through a soundbar is free, or if it requires purchasing an app from the Microsoft Store?

Thanks in advance for your help!

Best regards,

If your games already output Atmos then you do not need the app. The app from the store is only needed to convert non-Atmos sound (like stereo sound or DTS sound) to Atmos. If your monitor has an HDMI input and eARC output then it might be better to connect the gpu hdmi to the monitor and the monitor eARC to the soundbar.

You need to install Dolby Access for Dolby Atmos to work. But no need to purchase it. It is free for Speaker systems. Only need to purchase for Headphone.

That would be output as Spatial Audio not Dolby Atmos unless we set it to it. Atmos has bit better processing than Windows Spatial Audio.

Thank you for your feedback regarding the Dolby Atmos software on Windows.

My monitor is equipped with a DisplayPort connector, while its HDMI connector does not support eARC or ARC. Additionally, my future soundbar will have only one HDMI connector.

Regarding my specific need to use HDMI exclusively for audio and DisplayPort exclusively for video, is this feasible in the technical environment I have described?

 

[pierred512]

In other words, is it possible to configure this in Windows: specify that the audio output uses HDMI while the video output of the game uses DisplayPort, ensuring that Dolby Atmos sound functions without encountering specific issues such as latency, audio delay, or any other inherent problems with this setup?

See when you connect to Soundbar Using HDMI Port it shows up in the "Playback" devices list in "Sound Control Panel". You have to set it as Default. And then go into its Properties and if you have Dolby Acess Installed if you go into Spatial Sound Settings in the drop box your will find Dolby Atmos. You will have to select that and Apply. That be it.

Yes Audio will be passed through HDMI and video through DP.

Thank you for your response!
Can you confirm that all the functions of Dolby Access are free for use with a Dolby Atmos soundbar? Only the use of Dolby Access with headphones is paid, correct?
We agree on this point?

 

[pierred512]

More precisely, are there any Dolby Atmos features or advanced settings (which ones?) for a soundbar that are only accessible through payment for the Dolby Access software?

See it is not Paid for Soundbars and AVR setups is because with them it will only work if they support Dolby Atmos for which the soundbar or AVR manufacturer already pays the license fee to Dolby to include Dolby Atmos on them as a feature. So make sure your soundbar supports Dolby Atmos. Headphones manufacturers don't pay license fee to Dolby as that is not a feature they include on Headphones. Yes there are some specific headphones which are said to support Dolby Atmos for headphones and are advertised as such and those headphones come in box with included code for Dolby Atmos for Headphones purchase.

Anyhow you don't have that headache with Soundbars AVRs etc. Just make sure it says that it supports Dolby Atmos.

Excellent! Thank you very much for your clear and detailed response.

I was told that, for example, in the case of the Sonos Beam 2 which has a single HDMI eARC input, it would not work because it requires an eARC signal input, and a graphics card cannot produce such a signal (unlike a compatible TV offering an eARC output). Can you confirm this or is it incorrect?

 

[pierred512]

If that is the case, a Sonos Beam 2 would not be able to work with my RTX 4070, my 4K monitor (which lacks an eARC output), and Dolby Atmos.
And the same problem for a system: SONOS ARC + ERA 300 x 2 + SUB (Gen 3)?

Yes it won't work as HDMI eARC port is a HDMI OUT port and not a HDMI IN so it won't take in HDMI signal the usual way. Yes it won't work if that is the only HDMI port it has.

You be needing something like this for it to work where you run HDMI to this box and then output ARC signal to Soundbar. Which is an added cost.

5. Does NOT support Sonos-ARC/e-ARC.

It is explicitly stated that this device does not support Sonos ARC/eARC. (what I am looking for, in fact)

Yes bit expensive but seems to work with SONOS.

Thank you for your feedback. In your opinion, does the first device work for a soundbar with a single HDMI connector (which is ARC), but not for Sonos soundbars that might have an additional feature? And what could this feature specific to Sonos be?

No Specific feature. Just additional Pain. LOL. I think the signal coming in needs to eARC encoded and won't be enough if it simply carries audio like with the first one I mentioned. Seriously SONOS should not have implemented it that way.

This one encodes the Signal going to Soundbar as eARC. So it should work.

I currently have an older television that only supports ARC (and not eARC). It is connected to a Sonos soundbar via HDMI ARC. The Sonos therefore supports ARC well, and the first device seems to be compatible with this technology.
Would another soundbar, similar to my Sonos (that is, with only one HDMI,a HDMI ARC port), also not work with the first device?

May work or not. It depends. But seriously most other soundbar has second option of input support not only one. But yeah some work some don't. Hard to tell. Some simply accept audio over HDMI for its simplicity. Without the need of signal being ARC/eARC.
