ipad sound very low

This is me answering because i was struggling for ages for figure this out and once i did i realised that nowhere spoke on this. If your iPad randomly gets quite then i would go to sounds and turn off reduce loud sounds and also turn off change with buttons too then try it again because i have 2 kids in my house and we all use the house iPad so we can monitor what the kids do online and i found it that the reduce loud sounds feature was on and was 45 so couldn’t hear anything so just turned it off. Hope this helps someone.
