Town Co. agent noise won't stop :(

[cam]

Absolutely love this game, but I've had an issue with the go-go crossover NPC that I don't see mentioned anywhere in the discussions. The NPC visits my town a lot, which is fine but the sound won't stop going off when I'm just trying to do things around my house and town. It drives me absolutely bananas. I legit can't focus on what I'm doing because the sound is constant. Like I said, I adore this game, but I might have to take a break until the noise is fixed :(
