Whenever I plug in a headphone to my smartphone the sound keeps coming from the internal speakers

Hello guys, I guess the title is obvious ..
anyway I have a Huawei Ascend G610 .. when I plug in any headphone .. the sound never comes through it .. it keeps coming through the internal speakers ..
I need a solution except resetting my phone ..
thanks in advance ..
