The headphone socket on my old Traktor2 Mk2 has developed a fault which has steadily got worse. At first, the stereo split would occasionally drop on one side which was a bit of a nuisance, but by wiggling the headphone jack the stereo sound would return to normal. However, it's got to the point where it's almost impossible to hear any music in my headphones, and wiggling makes no difference. I'm assuming the socket itself is failing. Is this a repairable fault? Everything else on the controller is fine.
