FMOD::Studio::EventInstance setvolume issue

FMOD::Studio::EventInstance setvolume issue
After start, even if I set it to setvolume(0) immediately, I hear a “tick” sound.
This is not a normal sound.
Not all of them are like that, but it occurs in those where the Event starts from 0, as in the attached screenshot.
The fmod engine used is 2.02.15.

There should not be any “ticks” unless of course there is enough time between the play call and setVolume that the event is audible.

I tried to reproduce it myself but have not been successful, are you able to share how you are playing and controlling the event?
