Comment 3 for bug 1498466

Specifically, iOS's "Ringer and alerts" slider is followed by a "Change with Buttons" switch. When off, it has a caption: "The volume of the ringer and alerts will not be affected by the volume buttons." When on, the caption is: "The volume of the ringer and alerts can be adjusted using the volume buttons."

Until now I had never understood this setting, because none of that text answered the vital question: What is the effect of the off state? When the switch is off, what *do* the volume buttons adjust? From testing it now, it seems that when it's off, the volume buttons always change media volume. When it's on, the volume buttons change media volume when media is playing, ringer/alert volume when media isn't playing, like the specced-but-unimplemented Ubuntu behavior.

Anyway, I don't think System Settings is relevant to this bug, because you shouldn't have to switch to System Settings and back while playing a game.
