Audio playback stops

[Android Central Question]

Whether I am listening to an audio book or music, playing stops a couple of minutes after I lock. I randomly get a popup overlaying any screen saying Close apps after screen lock has stopped with an X and Close app, which seems like it could be related, but does not offer any options. I can't find anything in settings.
