Immersive Audio missing in Davinci Resolve 18

Downloaded update from version 17 to 18 today.
I want to create a project using Dolby Atmos, but the immersive audio setting is missing. See attachment.

Help like a link or a manual would be appreciated.

Do you have Studio?

Go to Preferences/Video and Audio I/O, and the Fairlight page.
Page 3619 of the latest Resolve 18 manual.

I have free version. Then I understand that I have to upgrade.
Cheers for the infos.
Case closed.

Hello,

I do have Studio version 18.1.2 build 6.
Same problem as Severin : no immersive audio settings (see her screenshot)
Preferences, Video And Audio, immersive audio : Enable Dolby Atmos is checked.
Right now, I only have 2 speakers connected (left-right) : could this be the reason ?

Page 3619 of manual is about bands 1 to 6 and 2 -5.

Post a screen shot of the About window, Didier.

Hello Jim,

Here is a screenshot of my Davinci About Window.
I'm also using the speed editor.
I'm running Windows 11 22H2.

Didier, sorry I got the page number wrong. Look at page 3706 in the manual.
