Does an iOS app with background audio run when not playing audio?
<p>Does an iOS app which declares using background audio run indefinitely?  Or, is its lifecycle tied to <code>AVAudioSession</code> being active?  Or, is it tied to audio playback being active?</p>

<p>I want to know what happens when you stop audio in a background app.  Is the app then eligible for termination?</p>

<p>I'm only interested in iOS 8 and 9.</p>
