I have googled this to death and came up emty ... unless you are developer or coputer geek.
The solution is: App called Timeriffic
Easy to use, and you create profile that f.ex. shuts down notification sounds from 23:00 to 6:00, lower ringtone, disable vibration and all the stuff you like to edit.
Then f.ex. at 6:00 you enable ringtone 100%, notification tone 100%, vibration and stuff you disabled over the night
Excelent stuff !!!!!!!!
