mobile

Hello everyone. I like to have a program to control the volume of the mobile. I tried several programs where you can create profiles for different situations controlling the phone volume, notifications, system, etc .., but at all when I change the volume of calls, I automatically change the notification and system, ie they are as united and if I change the previous notifications are modified too. I wonder if anyone has tried this type of program has worked separately. Comment I am root.
Thank you.
