Hi Fmod Team,  
I was using a sidechain output to drive a parameter in Fmod Studio, which is used to modfy volume levels of another track.  
It playsback fine in Studio.

In Unity, the parameter value doesn’t change and the track setup to have it’s volume changed by the parameter doesn’t alter.

Its all working in a project in 2.02 + Unity.

I think somethings changed or a bug’s crept in - happy to send over the project files if it helps.
