    The earliest 2019.1.X version that has Ducking working again for me is 2019.1.9f1 for me. All versions below that one still don't show input signal in the Ducking effect. (Tested unsuccessfully in 2019.1.0f2 and 2019.1.8f1, so I assume everything in between is broken as well)

    It says fixed in 2019.1 but it's not, I can still see this in 2019.1.4f1.

    Can this be backported to 2019.2? It's an important issue for us :)
