Found the solution in older thread from last year.
As my Volume OSD and Clementine the multimedia keys weren’t working.
Posted here as was having the same issue today Jan. 13th 2015 9 months later. As still in the repo, As solved my issue of multimedia and OSD voulume on screen not working by removing offending package. Just wondering why it’s still being installed if not needed and causing issues with some users.
