The reason the fn + audio keys don't do anything is that the commands in
~/.config/openbox/lubuntu-rc.xml are lik
<command>amixer -q sset Master 3%+</command>
<command>amixer -q sset Master 3%-</command>
<command>amixer -q sset Master toggle</command>
The problem with this is that amixer can't find anything on my system
with the -c1 option there.
Another problem is taht while toggling master off mutes everything,
toggling it again does not unmute everything.
So, I changed these things in lubuntu-rc.xml to invoke these scripts (I
got some of the ideas from someobody else's post from somewhere else)
volume_up.sh:
#!/bin/bash
CURRENT_STATE=`amixer -c 1 get Master | egrep 'Playback.*?\[o' | egrep
-o '\[o.+\]'`
if [[ $CURRENT_STATE == '[on]' ]]; then
#amixer -q -c 1 set Master mute
cd . # just a noop
else
amixer -q -c 1 set Master unmute
amixer -q -c 1 set Headphone unmute
amixer -q -c 1 set Speaker unmute
fi
amixer -q -c 1 sset Master 3dB+ unmute
volume_down.sh:
#!/bin/bash
CURRENT_STATE=`amixer -c 1 get Master | egrep 'Playback.*?\[o' | egrep
-o '\[o.+\]'`
if [[ $CURRENT_STATE == '[on]' ]]; then
#amixer -q -c 1 set Master mute
cd . # just a noop
else
amixer -q -c 1 set Master unmute
amixer -q -c 1 set Headphone unmute
amixer -q -c 1 set Speaker unmute
fi
amixer -q -c 1 sset Master 3dB- unmute
toggle_mute.sh:
#!/bin/bash
CURRENT_STATE=`amixer -c 1 get Master | egrep 'Playback.*?\[o' | egrep
-o '\[o.+\]'`
if [[ $CURRENT_STATE == '[on]' ]]; then
amixer -c 1 set Master mute
else
amixer -c 1 set Master unmute
amixer -c 1 set Headphone unmute
amixer -c 1 set Speaker unmute
fi
% changes iin volume work too, i just like the progression with +/- 3dB better
