虽然安装了acpi-support，但我的笔记本依然不能启用静音切换的快捷键，很不方便，于是自己写了个切换静音小脚本。至于调节音量，类推就行了。

# /etc/acpi/events/mutebtn
# Called when the user presses the mute button

event=button[ /]mute
action=/etc/acpi/mute.sh

#!/bin/sh
# /etc/acpi/mute.sh
vol=`amixer | sed -r "s/(\[|\])//g"  | sed -rn "/'Master'/,+6{h;/Playback.*%/{p;q}}" | awk '{print $5}'`
if test $vol != 0%; then
    echo $vol > /etc/acpi/volstore.dat
    amixer set Master front 0
else
    vol=`cat /etc/acpi/volstore.dat`
    amixer set Master front $vol
fi
exit 0
