* M: modify the default stream volume @{

public static final int[] DEFAULT_STREAM_VOLUME = new int[] {

4, // STREAM_VOICE_CALL

15, // STREAM_SYSTEM

12, // STREAM_RING

12,// STREAM_MUSIC

12, // STREAM_ALARM

};

2，修改mediatek/frameworks/base/media/audio/java/com/mediatek/audioprofile/AudioProfileManager.java中

final int DEFAULT_RINGER_VOLUME_SILENT =0;

final int DEFAULT_RINGER_VOLUME_MEETING =0;

final int DEFAULT_RINGER_VOLUME_OUTDOOR =15;
