I have a pair of Sennheiser HD555's headphone that I use on the onboard part of my motherboard's sound area and the tip of the adapter recently broke off into the green jack at a slanted to the right angle; I have tried absolutely EVERYTHING in my power for the last 3 day's to pull that sucker out with no success so I'm not going to even try that again. What I'm hoping and trying to do is to disable the back and use my top sound port or make the blue jack work like my green one. I've had no success on either. I'm using a Bio-Star 790GXBE and an CM690 case, can anyone PLEASE offer any help? Thank you.
