I'd like to add more information as it might be useful. I followed Tudor4 in http://ubuntuforums.org/showthread.php?t=2022151 by: push an on/off button of the laptop, then in a pop-up, click the shutdown (yes the shutdown, not the restart), then push an on/off button of the laptop to start up the system again, then the headphone works.
