Audio doesn't change with the scene. What are the settings for it? Thanks.

Hi,
My issue is that my audio doesn't change with the scene. It just keeps playing. I've been using OBS for many years now and I'm sure this is not usual behavior. In the past when I had changed a scene the audio stopped allowing only the audio for the next scene.

Their must be a setting for it, right? What is it? Thanks in advance.
