[Audio Driver]使用震动喇叭，在home界面通过音量键调音量，结果调的是媒体音量而不是来电铃声的音量
[DESCRIPTION]
问题：使用震动喇叭，打开mtk_VIBSPK_SUPPORT，通过音量键在home界面调节音量，经常出现按一下没有提示音的情况，观察音量图标，发现调的是media的音量等级，而不是ring的音量等级。进入setting，把震动关掉，此问题就不再复现。只要是在震动的时候去home见面调音量键，就可以必现这个问题。
[SOLUTION]
原因：这是因为震动的时候会播放一个silence，stream type用的是music，当在home界面调音量的时候，会去底层get stream type，如果此时在震动，则会get到music的stream type，所以会变成调节的是media的音量等级。

解法：请做以下修改(以下修改处以"AAAA"标识)：
1）修改/alps/system/core/include/system/audio.h
/*Audiostreamtypes*/
