When I install pavucontrol, there I am able to switch sound output on running application (including firefox). But later when I change setup (turn on or off my TV) then I must do it again this way.
Therefore I am unable to control my sound output using built-in sound controls in ubuntu (gnome) desktop and only possible way is to try another applications.
Found temporary solution.
