Windows 10: Dolby Atmos no longer works - Only plays stereo

A few weeks ago I was enjoying Dolby Atmos on my Windows PC , however I came to try Forza Horizon 4 again today and noticed something very strange. When I activate Dolby Atmos, my AV receiver (Denon AVR X4500H) says "Stereo" on its front LCD.


When I go to speaker test and test the surround sound speakers, the rear audio comes out the front speaker (e.g rear left comes out front left).


My specs are GTX 1080ti, Windows 10 pro build 1903 18362.356, Intel i7 4ghz, 16gb RAM


I've reset and removed the Dolby Access app, reinstalled my graphic card drivers, even reset windows, nothing will fix it.


The standard 5.1 and 7.1 audio options DO still work and produce sound as expected.

Dolby atmos no longer working!

I just installed fcu on my rig and lost my atmos in formats that arent atmos. My receiver is now showing dolby surround for non atmos streams like games music and internet. Everything showed atmos when there was sound pre fall creators, now it only shows
dolby surround. Was atmos removed on non atmos content?
