I don't think so, but I have considered this and I did try to "adjust"
the contacts with a screwdriver, truth is, I wasn't sure what
adjustments to make, other than just tightening up the port with some
slight pressure from a pair of needle-nose pliers. Is there a more
specific way to test/adjust the headphone jack?
