The worst volume control UI in the world (2017)
I think the worst UI is simply the Teams one, because it presents as an app volume control but then simply controls the <i>global device volume</i>. Fuck off, you are not the only app running.<p>But that comes second to the microphone gain control, which Teams similarly exerts unilateral control over - only this time through an automated algorithm that for some microphone types just ends up muting them entirely. It's wild, you can go into the Windows gain control settings and see the slider wiggle around.
