When dragging sound to "On", switch becomes "On", but slider goes back to 0% and has to be set again

[Wise Melon]

I have recently noticed that in the gnome-control-center in the Sound section that if I have something muted so that the switch next to the slider is set to "Off", and then also the slider set to 0%, that if I then drag the slider to a state where it would be "On" rather than muted, the switch becomes "On", but then the slider no matter where I drag it to returns to the beginning where it is 0% and then I have to drag it again in order to set it, so it seems that switching the switch to "On" results in it going to 0% in certain circumstances. Also please note that at no point in this process, not even when I turn the sound off do I touch the switch, only the slider.

Yes, I'm seeing this Xenial. Minor but should be fixed.

Nikita, can you file this bug upstream as well
