Headphone on Dell Vostro A860 (Conexant Cx20561) not work!

Hello
I have a Dell Vostro A860, some month ago decide to install Opensuse 13.1 on this and i installed!!!
Everything was fine, even headphone, but after some week, i lost this feature :frowning:
Now my laptop Speaker and mic work very well but i can hear anything with my headphone;

Can somebody help me to hear music with headphone again? :frowning:

Thank you…
