Implementation is silly. The idea is not bad - I actually need something of the kind, a key to press when I want to switch from headset to speakers and back (as I play music and talk on skype on the same machine). But if I have to plug the headset in and out to achieve that, then this is no better than it was 50 years ago, when plugging the headset in would turn the speakers off. If it's asking for this, it's offering to keep the speakers on, which is fine if you want that, but asking for it every time is downright silly. And having to navigate through active apps and menus to turn that on or off is equally silly if not simply unusable - I want this to be one click (I'm responding on skype, switch to headset; I've finished, switch to speakers) or two clicks (one to respond to skype, other to switch headset/speakers - the latter being what I may want to skip sometimes). Similarly the gamers may want to switch at times between speakers (solo mode) and headset (team mode, communicate with mates).

There's a whole area of user interface in this regard where they have made almost no progress in the last dozen years.
