When you touch and hold a notification on the status bar, there will be two options that appear “Prioritized” and “Silent”.
1). Select “Prioritized” to allow a sound alert for this app and subsequent new notifications.
2). Select “Silent” to mute all notifications for this app.
Other options. Go to Settings > Apps - select the Messages or your email client, then tap App notifications to see whether sound notifications are turned on or off for the app.
