Are you talking about default level on boot or the ability to change the volume? – Nir Duan Jul 20 '16 at 06:47

It may be irelevant for OP, but for anyone other, if you mean set the volume to max like you do in settings, there is an array default stream volumes in AudioManager ( or AudioService - don't remember in which of them ) which you could modify. Make sure to check the other array containing the max values for each stream. – Rick Sanchez Nov 08 '18 at 12:19

There are two main places I would look for:
1. /frameworks/base/core/res/res/values/config.xml
Inside you'll find the config_soundEffectVolumeDb which control the default volume.
But AOSP developing is never that easy - This file might be overwrriten by specific vendor so you will have to chek here too:
2./device/<companyname>/<productname>/overlay/frameworks/base/core/res/res/values/config.xml

Big answer - no. From what i managed to understand it will try to take to the higher level and will get "stuck" on max – Nir Duan Jul 20 '16 at 08:21
