Sidechain level in the mixer doesn't work in game

If you open the preferences dialog and navigate to the “interface” tab, is the “synchronize changes upon connecting to game” checkbox checked? I ask because, in theory, this checkbox determines whether the state of effects in your game are updated to match those in your FMOD Studio project when you connect to your game using live update. Knowing how this property affects behavior might help shed some light on this issue.
