"Active", in what way? Visible, sure- affecting anything else, not sure about that. Have you turned off the app? Can you even do that on an Android?
Closed out app. Phone shows nothing for app being open. But, if you go into app manager and force close, the volume slider will disappear, so the app is staying open in the background. The only setting I see that might affect this is network standby, but disabling this will result in not being able to power the system on from the app.
