** Description changed:

  I have a Fujitsu Siemens Esprimo Mobile Laptop (X9525) with a docking station. After I updated to Ubuntu 9.10 I encountered problems with the sound system. When I plug a headphone to the laptop, I can still hear sound via the speakers. I am not able to get rid of the sound of the speaker when plugging the headphone to the laptop. However, when I plug the headphone to the docking station, everything works as expected and the speakers are switched off automatically. 
  When using the audio applet in the taskbar and setting sound output to "analog headphone" I only have sound via the docking station but not via the laptop headphone jack or the speakers. Only when setting the sound output to "analog output" I have sound via the laptop headphone jack (and also via the speakers).
