facing issue with Rhythmbox control panel. I am unable to pause or play next song from control panel of Rhythmbox music player
For the indicator sound menu to work correctly you need to ensure that the MPRIS plugin is enabled:
Move you mouse to the top of the screen and choose the Edit menu and its Plugin submenu. Tick the option shown.
If you cannot see the MPRIS D-Bus Interface plugin then it is likely that you do not have the
rhythmbox-plugins package installed.
In a terminal type:
sudo apt-get install rhythmbox-plugins
