Using Mute, Lower Volume, Raise Volume keys (Asus eeepc 1005PEB)

onexused · 2011-09-09 22:39:09

I'm trying to set fn-F10 to mute the volume, fn-F11 to lower the volume, and fn-F12 to raise it (this is what's printed on the keys) but I'm having problems.
I'm using LXDE and openbox, but I have xfdesktop (if that affects anything).
First of all, these keys don't "just work".
I can set fn-F10 to output "f": $(xmodmap -e 'keycode 121 = F') and I can set left arrow to output XF86AudioMute: $(xmodmap -e 'keycode 113 = XF86AudioMute') (which, incidentally also makes fn-F10 output the same) but when I try to set 121 to output XF86AudioMute, it doesn't output anything, according to xev:

KeymapNotify event, serial 37, synthetic NO, window 0x0,
    keys:  4294967210 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

121 - 123 are the keycodes (plus 8) for fn-F10 - fn-F12 given to me by showkey.

What can/should I try? I already have the appropriate entries in ~/.config/openbox/lxde-rc.xml.

Maybe take a look at xbindkeys

All this doesn't matter 'cause I'm an idiot. Everything was working, but the command in ~/.config/openbox/lxde-rc.xml was toggling the master channel's mute on the alsa card and I'm using PulseAudio, which is what I control from the lxde panel applet.

So the question now is, what command can I use for Pulse instead of ALSA? I assume amixer is ALSA-only.

[ignore]
For whatever reason, the fn-keys and the actual keyboard show up in two different input devices. This might have had something to do with xmodmap horking, but it's irrelevant now.

$ ls /dev/input/by-path -l

As long as you are using ALSA as a backend, you can use the following commands:

amixer -D pulse set Master +5% unmute
amixer -D pulse set Master -5% unmute
amixer set Master toggle
