Please help with Dolby Atmos

Cubase
1

Hi all. I have Cubase 12 Pro.

I found out about Dolby Athmos object panning and wanted to give it a try.

After I set it up and made a mix, I ran into several problems, namely:

  1. I don’t understand how to turn off the Dolby Athmos renderer now and return Stereo Out in the project where it was connected.

  2. When I create a new project, for some reason it also opens with Dolby Athmos already connected, and I don’t know how to fix it.

  3. I exported a Broadcast Wav File and I don’t know what to do with it. I don’t know how to reproduce it, how to open it, how to convert it.

Even when I import it back into Cubase it doesn’t play.

Please help with advice or instructions.
Thank you.
