Electric outlet not working
This sounds like a bad "backstab"

It sounds like the receptacle that's crackling was wired using "backstab" terminations, which are rather failure-prone, as you're finding out the hard way.  Re-doing the crackler using a new receptacle, proper pigtailing, and the screw terminals will make all your problems go away -- just remember to turn the power to the circuit off at the breaker first!
