Windows 10: Dolby Atmos for Home Theater, No Sound with AVR

Hi all, recently I received an AVR + Speakers & Sub from someone who did not have use for it anymore. I've been trying to use it with Windows 10 using "Dolby Atmos for Home Theater" selected under spatial sound. However, whenever I choose it, I don't get any sound whatsoever from my speakers. I've also noted that when I choose Atmos and try to change the volume in the lower right corner, my AVR displays "Dolby TrueHD," yet as I mentioned before, I get no sound even though Windows shows that sound is being played. I've downloaded Dolby Access, and whenever I play a test video, sound works perfectly and my AVR displays "Dolby Digital Plus." I've scoured the internet for other people who had similar issues, but no methods have proved to be a solution. Any help would be appreciated because at this point, I'm losing my sanity by the minute trying to get this damn thing to work haha. Please let me know if I'm posting in the wrong subreddit or if I should post this elsewhere

Dolby Atmos for home theater option is missing.

My set up: I have Denon AVR X4400H connected to my Nvidat Titan x (Pascal) via an HDMI cable. I have my monitor connected to it via the display port cable. I have 5.1.2 speaker set up connected to the receiver and they all work fine.

Denon is the default playback device. When I attempt to go to spacial sound, I do not see an option to enable Dolby Atmos for home theater. I only have an option for headphones which I can enable and it works fine as far as I can tell. When I use Atmos for
headphones and play Atmos content from the Dolby Access app, my receiver displays Dolby Atmos as the source input type.

I've tried reinstalling Nvidia sound drivers and Dolby Access app to no effect. The option to enable Dolby Atmos for home theater is missing.

I want to try dolby atmos sond on PC and looked inti windows 10 dolby access dolby atmos for home theater. I searched atmos sounbars and find all atmos sonndbar pair with receivers. I

I find this Pioneer Surround Elite Atmos Soundbar is one of the budget range. dolby access dolby home theater need dolby atmos enabled home theater or soundbar. All atmos home theater paired with receiver. I contacted support and they said the soundbar
would not output audio without connected to to recriver. All ports on the receiver are all ocupied The only port left is HDMI out (ARC) for connect to TV.

if dolby atmos for home theater only support HDMI on home theater, how can it conned to PC HDMI ?

 

PC to AVR no audio output when Atmos

Recently my setup stopped producing sound. When sound was playing, my AVR would show "dolby surround" when playing games and watching youtube. I left my computer on for 24 hours. When I came back, my AVR would say "dolby atmos" when playing games and youtube. Unfortunately, no sound is produced when it says atmos. Sound is produced If I configure the setup to 5.1 with no spatial sound. In this scenario, the AVR shows "multi ch in."


I'm fairly new to PC ownership. I have my PC set up like a console to my home theater and TV. The PC is connected directly from the GPU to the AVR using an HDMI 2.2 cable. My AVR is a Denon x2300 that supports Atmos encoding and decoding.

It took me a while to fumble my way through setting it up originally. The steps I have already taken include: making sure all windows updates and drivers are up to date, using the "configure" settings, downloading the doldy access app and setting it up for home theater, and using properties menu to set spatial sound to dolby atmos.
