The main reason why music pauses when closing Facebook is due to a bug or behavior in the Facebook app where it interferes with background audio playback. Facebook's autoplay of videos and sounds takes audio priority, which leads to other music apps pausing when Facebook is opened or closed. This issue has been reported widely across iPhone models and iOS versions, and can even occur when no video is actively playing but Facebook is closed or minimized. The problem is often caused by Facebook possibly misusing media playback APIs, causing the app to kill background audio from other apps when switching away from Facebook. To stop music from pausing, a common recommended solution is:
- Turn off video autoplay in the Facebook app settings.
- Disable in-app sounds in Facebook.
- If the problem persists, uninstalling and reinstalling the latest version of Facebook usually fixes it, as Facebook has released updates addressing this bug.
This issue is specific to Facebook and does not happen with other apps, and it is a known bug being actively addressed by Facebook through app updates.
