That sounds like EMO’s chat online scheduled event. That’s normal and he’ll keep doing it for a few minutes until the next event in the schedule or the time the animation plays completes without interruption.
Right now there’s no way to turn off scheduled events. You can mute the schedule sounds under the preferences tab in the app but that’s about it.
