从log进行分析, 主要原因是蓝牙传过来的音量为19(50%)导致.
以下为音量传过来的调用栈.

这个音量是蓝牙模块设置的.
从代码和现象看, 好像是正常的表现行为(似乎50%的音量还在是在蓝牙的VolumeManager.java中处理.).
但需要蓝牙模块确认下, 是否为正常的表现行为.
什么样的场景蓝牙的音量才会进行保存.
多谢!

更新:
蓝牙耳机设置的音量保存在下面perfeence文件中.
cat /data/user_de/0/com.android.bluetooth/shared_prefs/bluetooth_volume_map.xml
<map>
<int name="54:0E:2D:00:9F:C6" value="32" />
</map>
在断开蓝牙设备,和重启设备前, 系统会把保存当前用户配置到这个文件中.
我这边复测了几次, 概率性存在设备没有保存到这个文件中情况. 如果文件损坏,会设置默认值. 下一步, 确认在重启前后, 对用户设置音量的保存情况.

该问题原始是：
重启时，设置的音量概率性未保存下来。
修改为：在每次变更音量，及时保存设置（原处理逻辑：在耳机断开和关机时保存）

已和测试确认, 这个是不同的耳机的兼容.
使用Vivo TWS Neo, 爱国者 测试没有问题. OPPO Enco WS1 有问题.
该问题是在修改音量的时候保存音量设置到xml文件中. 对于不支持Absolute volume 的耳机未修改到.

Hi 赵飞， 王成， 小刚
上面patch修改已包含（不支持绝对音量的耳机）， 请帮验证．
（该问题提票时，未说明耳机型号，我们这边分析用的是Vivo TWS Neo耳机，后测试OPPO有问题（不支持绝对音量），原patch未覆盖到．先已包含 ）
谢谢！
