HP Pavillion G6 2213sa

Hi, my latop which i've had since Febuary of last year has started having some hardware failure with the headphone jack, i'm having to prop my headphones into position with tape to get it to play through the headphones rather than headphones and speakers at the same time.
I'm wondering if there's anyone who could tell me what the cost of repairing this would be or where I could get this fixed, my warranty expired in December but has been sent off for repairs within its warranty
