[SOLVED] Problem with Headphones

Hi, I’ve just installed Netrunner on my Dell Inspiron 17R-5737 laptop and I have a annoying problem with headphones.

When I plug them the speakers mute automaticaly (which is good) but there’s no sound coming from the headphones.
If I change from speakers to headphones in Phonon settings I can get it to work but I want that to happen automatically.

I appreciate any help, thanks.
After a serach in the forum I found a way to solve my problem:
