@David, now I hear sound on external speakers. But I have new problems.
First problem: I set volume to 100%. But when I plug in speakers volume is not the same so I have to go pavucontrol and manualy increase/decrease volume. Video of the problem: http://www.youtube.com/watch?v=ps7_zLvHUpQ
Second problem: Sometimes after I unplug external speakers, volume (loudness) of sound on laptop speakers is very low although it is set to 100%. Video of the problem: http://www.youtube.com/watch?v=0ebnQ1m6knQ
