Galaxy s7: Random static noise after Nougat update

[AC Question]

My Galaxy S7 is about a year old. I've never had a problem with crackling or static until Nougat update two days ago. Now I get this weird crackling-static noise that happens randomly throughout the day, even when I'm not using the speaker. Anybody have a fix for this?
