Manual duck not works

[Rafal Zak]

Option "Manual duck" seems to not work at all, while using Microphone to broadcast radio. When I press "Talk" background music level doesn't change - on recorded "audition" results of "Manual duck" and "Duck off" are completely the same.

System: Windows 10 Pro
CPU: Intel i5

Thanks for reporting this bug.

Which skin do you use?

Manual ducking lowers the volume of everything but the mics by the amount determined by the ducking Strength knob. If you want to adjust how much the music is reduced in volume, turn the Strength knob.

I poked around a bit in the enginetalkover code, just to find out that the Strength knob works exactly the opposite in AUTO mode than it does in MANUAL mode:
MANUAL strength=0 > max music ducking, strength=1 > no ducking
AUTO strength=0 > no ducking, strength=1 > max ducking

This is confusing and also not reflected in the tooltip.
We should decide for eiter way, and I find the way it works in MANUAL mode right now more intuitive: Strength knob is kinda like a music Vol knob.

Don't know if that's the issue @zaczy experienced, but it's a bug.

That is confusing. I think it would make sense to invert one of them.

I think we should backport your fix to 2.2 as well.
