How to connect headphone to LCD permanently?

I have a 40 inch 1080P full HD series 5 LCD which is wall mounted, now at times I wanted to connect a audio headphone to this LCD. the audio jack is at the rear and it's very difficult to connect & disconnect every day, if I do not remove the headphone from the LCD then the TV speakers are disabled (no sound from TV speakers until I remove the headphone), I need to know, how to have both the options (sound through TV speakers & through Headphones) available with me at any point of time, kindly help.
