I discovered this when I organised my menus into logical categories instead of the menus been monolithic.
To reproduce try the following;
Create a new menu called Multimedia in System > Preferences
Then copy over the following items from within Preferences into the new Multimedia menu;
Sound Volume Control Multimedia Systems Selector
Once these have taken effect the same items should then appear in the Applications > Other menu
This also impacts in the Open With context menu, by duplicating entries for apps that can be used to open file MIME types.
