Ramp down to volume

Hello ,

I would like to make a scene where the volume goes slowly down to 0.
I think I can do that with the "ramp down to volume"in the advanced section of a scene.
For the moment I can not get it to work , anyone has an idea?

Attached a screenshot of the options

Thanks,
Cor

Does anyone have an idea how this works?

Thanks,

This would engreat if it worked.
Bump.

It looks like it doesn’t work , or I am doing something wrong with the settings.

It would be nice if I could get this function to work.
