Pogo pins expose power and I2C for expansion devices whenever anyone gets round to making one. They don't have anything to do with the headphone jack, and nothing is using them by default. However it's possible that if one of them has come apart that one of the parts has got somewhere and caused a problem. It's also possible it's just a software issue with activating the right audio profile, especially as it's early days for the new hardware revision.
