I had have a problem with headphones sound switch on my MSI GX600PX-12EU notebook. When I plug headphones, sound was active on speakers and headphones both. This was a problem when I listen a music while working in the same room with somebody.

I found cool and easy solution to fix this problem.

You need to open text editor with root permissions and edit file /etc/modprobe.d/alsa-base.conf
You can do this with hit
ALT+F2

and type

gksu gedit /etc/modprobe.d/alsa-base.conf
At the end of file add
1. # headphones sound switch fix
2. options snd-hda-intel position_fix=1 model=targa-2ch-dig
You Must restart your computer
Try to play some music and plug headphones.
If nothing happened, check if Volume Control > Preferences 'Headphone' option checked.
