我这儿 amixer get Master 的输出是这样的：

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 11142 [17%] [on]
  Front Right: Playback 11142 [17%] [on]

所以像现在代码里那样 grep Mono 的话拿到的是空行，不能获取音量。

不知道是有bug还是 amixer 不同版本、平台下的表现不同。前者的话我这儿已经改好了一个版本，可以发个PR上来；后者的话，需要考虑一下更可靠的音量获取方法了。
