status/volume: Show OSD volume slider on plugging unplugging headphones

OSD Volume popup appears when a user connects or disconnects
earphones/headphones/headsets.

Shows and warns the user that the volume may be set to high
or low when headphones are connected or disconnected.

This is a nice bit of feedback to the user that something has
changed, and something that other platforms do.
