Where is the volume settings file in Android 4.2.2?

Question

Android

Good afternoon.
I ran into a problem - after rebooting the device based on Android 4.2.2, the volume level, set to the maximum, is rolled back to the factory values.
I would like to try to change it manually in the OS itself. In this regard, I would like to know where the file with these settings is located?

Is there root? Have you tried searching yourself?
