Continues notification sound without any notification

[TaRello]

I have a continuous notification sound (coins sound), i disabled all notifications, all advanced setting in accessories also made mobile on silent mode 

Even No notification history appeared

I downloaded a couple of notification app to capture any, but nothing appeared ‼️

Finally it is from 8am to 8pm‼️

Activate Do Not Disturb mode and turn off all notifications .. If the following solutions dose not work, make a factory reset

Unfortunately after don't disturb, still as is...
Does reset factory settings, remove all mobile data i.e media....
Or just the settings.
