Dolby Atmos on a PC

[nzoomed]

have you seen this page
https://games.dolby.com/atmos/pc/

it kind of suggests it's built into windows 10/11 in the form of Microsoft Spatial Sound

I also see a fairly comprehensive writeup on this reddit
https://www.reddit.com/r/hometheater/com...indows_10/

which seems to reference this app

HTH

Yes you need to install Dolby access to enable it, i think all that does is encode the signal over the HDMI, but as far as I can tell, it wont work through an existing sound card with the speakers connected to it.
From what that reddit page suggests, it still needs to go through an HDMI AVR.
I was hoping I could avoid that, since I have been using my own custom amplifiers (I build a ton of tube amps)
