I've been having a similar problem with my front headphone jack. When I plug in my headphone sometimes there is an attenuated signal also coming out of my external speaker. If I jiggle the headphone plug I get get the speaker to eventually go off. I do have the K3 configured to disable the speaker with the head phone.
It looks like it would be tough to replace the headphone jack.
