how do you stop a sequence of sounds created with the Sound command?

We see the same thing in other places as well. Netflix can start playing a movie preview with the sound on, you can close the tab Netflix is in -- or even close your browser! -- and you'll still hear sound until the buffer plays out and finishes. Once it's in the buffer, I don't know of any way to get it out once it starts playing. It tends to have to just run its course.
