Adjust the volume of the media playback

SUPER-USER

The maximum volume of media playback is good,
but the minimum volume is too loud.
Is there a way I can reduce the minimum volume?

I read some time ago that you can adjust the volume in the developer options.
Unfortunately I can not find this report anymore.
Does anyone know how this works or can someone give me a description?



Edit:

uuuuhhhh... I found it.

Use the EngineerMode.
Dialing *#*#3646633#*#*

Change the music level

1. Scroll right to Hardware Testing and choose Audio
2. Choose volume Mode
3. Choose Audio Playback Mode
4. Select Music in the drop-down list of Type
5. Select speaker in the drop-down list of Type
6. Then I changed the volume Index 1 from  88 to  40
7. Then I changed the volume Index 2  to  90
