Adrien,I have had this sort of problem with a Fujitsu laptop at work.
I suggest spraying a drop of contact cleaner into the jack as it seems to be the leaf inside the socket which fails to break contact; switching off the speakers. Also plugging in and out the plug may release it.
Some headphone have a better fitting plug, so worth trying a different pair as well!
Hope this helps/works. Regards,Mike
