i3wm 調節音量

i3wm，設置調節音量的快捷鍵
configure file:
~/.config/i3/config
add

# for sound control  
bindsym XF86AudioRaiseVolume exec amixer set Master playback 5+  
bindsym XF86AudioLowerVolume exec amixer set Master playback 5-  
bindsym XF86AudioMute exec amixer set Master toggle  

x200上靜音鍵可用,調節大小的按鍵沒有作用

修改

原來是數值太小,修改為

# for sound control  
bindsym XF86AudioRaiseVolume exec amixer set Master playback 5000+  
bindsym XF86AudioLowerVolume exec amixer set Master playback 5000-  
bindsym XF86AudioMute exec amixer set Master toggle  

可以使用, 可用

amixer
