Marcus,
If I had to guess, this depends upon whether MobileSheetsPro is being paused by the operating system. On your device running 4.4.2, it sounds like MobileSheetsPro is paused, which stops a lot of things, including the audio player. On the 5.1.1, there are probably enough resources that the OS isn't pausing the app right away. Outside of me adding a new feature where the audio playback isn't paused even if my app is told to pause, I'm not sure if there is anything you can do to prevent this. If I was going to add a feature like that, I would need to research more on how to properly handle it. I think there is a proper way to handle background audio playback that I'm not currently utilizing.
