    Thanks to everyone that conributed to this guide. By the way my set up is, GTX3070 to an LG C9, eArc to my soundbar.

    I was getting so frustrated that my speakers were not working correctly, yet when the Atmos app installed, the speakers worked. I could get stereo fine, but selecting anyhing else meant centre and rears not working.

    Initially downloaded the Dolby Atmos app from Microsoft store when troubleshooting, which gave me the permanent "fake" Atmos reading on my soundbar, upscaling on all sounds to the speakers, but anything else selected in the sounds settings was boken. 5.1 and 7.1 would not play correctly, or give an unsupported error.

    Ran through the steps here and bingo! Sounds from all the speakers correctly (even identified that I had my rears the wrong way around)

    I then ran the Dolby Atmos app, played the Forza demo, it pops up saying Atmos not enabled, but my soundbar picks up the Atmos track and it works fine, so pretty happy.

    You said you followed "the steps" here.. but don't specify which ones... it would be really helpful if you could tell me which set you followed as there's so much here..

    Sure no worries,

    This first step might not be needed, but it's something I did to ensure a clean slate to work off:

    Download DriverStoreExplorer

    Releases . lostindark/DriverStoreExplorer . GitHub

    Extract, run Rapr.exe, wait 30 seconds or so for it to scan,

    When it finishes, scroll down to the "Sound, video and game controllers" section, select your Realtek and Nvidia drivers and select Delete Driver (and tick the Force Deletion box).


    Now follow this guide posted in this thread:

    Download the HDAudio pack from here: HDAudio
    Unzip and install APO driver, selecting "FX Configurator" and "Dolby DS1 7.6.5.1"
    Use FX Configurator to set the device you want to using Dolby Home Theater v4 (HDMI/SPDIF), illustrated here: https://imgur.com/AK0MMko]
    Install DolbyHomeTheater.msi from Fatguy's zip file
    Go to your device in sound window (looks like old control panel, not modern settings page), click properties, and if successful, you should have a "Dolby" tab and in Advanced > Default Format, a "Dolby Digital" format.

    Test surround sound via the 5.1 surround sound file Fatguy listed earlier via Windows Photos app (direct link here: https://www2.iis.fraunhofer.de/AAC/ChID-BLITS-EBU.mp4)

    All those links posted, when you click will come up with an error, remove the bracket at the end and you will see the images.

    To anyone that needs visual assistance I made a video explaining this a bit better while crediting the users in this forum.

    Fantastic, I am so glad I started this thread, love how the info is helping people get all the sound working that they paid for, the sound that they should be getting, and it is a big issue with so many people.

    I followed these instructions, to the letter, but still am stuck with only 2 channel audio sadly.. all i have as output options is stereo , dolby (new thanks to the instructions) or Dolby atmos home theater. Dolby Atmos home theater SORTA worked beforehand, but was horribly unreliable , but at least i could get sometimes 5.1 channel audio (it would die after a time for some reason)... but after following your instructions, I can't seem to get anything but stereo working. Is there a good way to "undo" / any other suggestions ?

    If you have a recent saved restore point, then yes, just restore that and everything you did is undone.

    @psiberfunk are you sure you are only getting stereo?

    Mine shows as Stereo in Windows, but play this test file and see if it's coming out in 5.1 on your speakers

    I know this thread hasn't been posted on for a while but I couldn't find any newer versions for this specific problem. I was able to get Fatguy's method listed below to work but randomly every 15-30 minutes the digital signal will cut out for a half a second and the digital decoding light will go on/off on my receiver. Has anyone else had this issue? I have changed HDMI cables/ports with no luck. I know the receiver is fine because when connected directly from the computer it does not do this but it only supports 1080 at 60hz passthrough. I have tried everything but dropping big money on a new receiver which I'm on the verge of doing if I can't solve this issue.

    Audio setup: Windows 11 machine with a gtx3090 > LG C2 > 10 year old Sony DA5700ES receiver through ARC. I was never able to get the youtube method here to work: Force HDMI to carry 5.1 Dolby (Solved) - YouTube . Some of the time Dolby Atmos would show up in the advanced sound properties drop down but would say codec not supported and disappear after a restart. I have spend many hours and attempts trying it.

    Fatguy method:
    Download the zip file from Fatguy
    Unzip and install APO driver, selecting "FX Configurator" and "Dolby DS1 7.6.5.1"
    Use FX Configurator to set the device you want to using Dolby Home Theater v4 (HDMI/SPDIF), illustrated here: https://imgur.com/AK0MMko]

    Not sure tbh. Does it drop when you're listening to it?

    Only issue I have is my Soundbar turns off after 30 minutes when there's no sound, and a lot of times I'll just browse the internet in silence. Now I use Soundkeeper which sends a constant signal that you can't hear - if you open the Dolby app you'll see a flatline - and my soundbar never turns off Sound Keeper v1.3.0 [2022/07/28] — VEG.BY

    Thanks for the reply. Yes, it does have the dropping problem when I'm listening to it. I'll give the sound keeper a shot. Thanks for the link.
