I'm assuming that this is a copper connection. There could be or may have been a mechanical issue with the cable contact that created or broke a ground loop. Possibly, the cable dress had been too close to a noise source and you accidentally now have a better route. Far fetched but possible: There is a current path crossing the two output jacks and jack B is closer to zero potential.
