Sounds like you either have a jack that has broken the solder connections to the circuit board or a piece of a plug came off and is stuck inside the jack or else you have a jack that the plug is just too loose due to age and slight bending of the parts that make contact inside the jack. Of course it might just be a bit of corrosion in the jack. I am assuming of course that the “popcorn” sound goes away when there is nothing plugged into that jack.

This does sound like bad jacks, no noise with nothing plugged in, same noise with different cables plugged in. I would replace the jacks with high quality parts.
