Possibly related: Assign some key-combination to "show player" (e.g. meta-p) in system settings -> keyboard -> shortcuts -> multimedia, press combination, watch as symbol in dash to the left wiggles but does not put focus on it. Very annoying when I want to quickly change songs without moving the mouse to the left screen border, wait until dash shows up and select player icon (or worse yet, when not having media player attached to dash, use the sound indicator *before* having to do those steps). I'm now improvising by attaching the media player to the dash and pressing meta+<number of icon> to make the player window appear and be in focus. Sucks, but it works.
