No ATMOS sound output with Samsung HW-K850 and Xbox One X

Hi

I assume you have paid for the Dolby App as you don't mention that you have. You need to purchase that in order to enable it.

Hello,

I just received my XBOX One X yesterday and attempted to set it up with my Samsung HW-K850 soundbar, which supports Dolby ATMOS. The XBOX is connected to the soundbar via HDMI (I've tried both inputs) and the soundbar connects to my Samsung KU6290 4K TV
via the only HDMI output from the soundbar.

For the audio settings on the Xbox, I selected "Bitstream" (HDMI) and then attempted to select the Dolby ATMOS for home theater option. I was prompted to download the Dolby atmos app, which I did. After launching the app, it basically directed me to to the
same thing I had just attempted to do - except this time, when selecting 'Dolby ATMOS for home theater', I got an error code: 0x80bd0009, saying something to the effect of, "There was a problem enabling that setting... Make sure your system supports it...".
The setting will nevertheless "stick" if I exit the audio setup screen and come back; it shows ATMOS selected - But there is NO sound output at all.

I've tried everything I can think of; moving the HDMI output from the XBOX to 1 or 2 HDMI IN on the Samsung soundbar; changing HDMI cables from the xbox-supplied cable (all are high quality, 2.0 version cables); tinkering with the sound output options on
the soundbar itself (surround on/off, etc); tried updating firmware on the soundbar (it was up to date); tried powering off/on the soundbar; unplugging the power from the soundbar and waiting 15 min; restarting the xbox; tried reinstalling the Dolby app. Nothing
helped.

All this being said, I am able to select the DTS option instead of ATMOS and get sound output - but I really want ATMOS

I would think this is some sort of xbox/soundbar communication issue via HDMI, where they're not agreeing on what sound format is acceptable. Any ideas?

Thank you so much!

Hi Ryan

The only thing you haven't mentioned is the HDMI output you are using from your TV to the sound bar. You need to be using the ARC (usually) HDMI 2 from your TV to the ARC input on the sound bar. Your XBOX should plug into one of the other HDMI TV inputs
on the TV so then your TV should operate as a passthrough for the ATMOS audio. Whilst the audio certainly sounds a lot better it is hard to know if ATMOS is actually working as a blue light is meant to show on the sound bar when its activated which is doesn't.
The audio improvement could just be the uncompressed bitstream provided from the XBOX.

Speaking with Samsung support yesterday as I was wanting to setup my LG C7 to play ATMOS via the built in Netflix App but NO why would they want that to be possible. After several frustrating hours trying to find how to get that to work I called Samsung
and got that answer. I had not asked them about the XBOX as I had not gone down this route before calling them.

I will be returning to the retailer today to have this conversation as they never mentioned the LG & Samsung units will not allow ATMOS to work.

Samsung support has no information on an update to resolve this but did say they had received several calls about it.

Im having the exact same problem: (

YES!

I have my Xbox One X connected via HDMI to my Samsung HW-K850 Atmos soundbar, which is connected via HDMI to my Samsung KU6290 UHD TV. For the life of me, I cannot get Atmos sound to work at all; There is zero sound when that option is selected in the One
X's audio setup menu. In fact, I do get an error code when selecting the Atmos option (0x80bd0009), but the selection appear to "stick" if I back out of the audio setup screen, then go back in. But there's no sound at all from anything. And I've searched here
and have found that others are reporting the same problem.

I contacted Microsoft support yesterday via chat, and after a long while, the advice given to me was to go into the VIDEO settings screen, and try selecting "HDMI" instead of "Autodetect" for the TV type. When I tried to change this setting, the xbox gave
me a warning that some/all 4K features of my TV may not work or be reported to the xbox - And that's exactly what happened. I was reduced to 640x480 resolution AND still no Atmos sound output.

The other recommendation, was to try connecting my Xbox directly to my TV, then use a 2nd HDMI cable to connect the TV (via ARC) to my soundbar. The issue here, is that my TV doesn't output 5.1 or Atmos via ARC - it only does 2 channel PCM. So that was a
no-go as well.

At this point, it is clear this is an XBOX communication issue with my soundbar. I know my soundbar can handle ATMOS; My Roku Ultra is able to send ATMOS to my soundbar just fine (I get the special blue LED indicator as added confirmation). I wonder if there
is any way to elevate this to Microsoft support to get a fix included in a software update?

I am having the very same issue. I've got the X1X, Samsung K850 Soundbar w/ Atmos, and OLED65B6... No amount of firmware/software updates, port switching, setting changes, or voodoo magic have been able to fix it. I did read online that one of the most recent
Insider updates has fixed the problem. I'm hoping to get an invite to check it out. Please update us if you find a fix!
