You can also find many of the settings in Sounds duplicated in the Notification settings for that app. It does not matter where you change them from, but it's usually easier to see them all together in the Sounds settings.
Went through all the apps. Culprit was Battery Doctor which rings when battery is fully charged. Thanks to you problem is solved.
