Tyler, did you ever find a solution to this? I'm having the same problem with a the same laptop (X1 Carbon 6th gen) running Kubuntu 18.04. The only "solution" I've found is to turn off "internal mic boost" using alsa-mixer (hit F5 to show all channels, cursor all the way to the right) and keep the mic capture level below 20%. So it works, but far from ideal since the mic is low (but better than making the person on the other end of a call hearing a shitload of white noise that's produced otherwise).
