Spectralayers an multichannel extension

I try to open Spectralayers Pro 9 as an extension in a 7.1.4 Dolby Atmos session and it doesn’t work. The file is a 5 channel. It is audible on the track, and Spectralayers standalone can play it in multichannel. But in extension, it’s silent. A trick?

p.s. Same thing with Melodyne Studio. So it’s ARA.
