The volume keys are not "standard" per se, which is why they often don't
work out of the box. I have not figured out a way to have them work in
CLI, but you can get them to work in X, using one of the following two
ways.
1) emerge xbindkeys
Read the documentation on xbindkeys to see how to write a
configuration file. On my Dell Latitude D600, the keycodes for
the volume keys are:
Volume up 176
Volume down 174
Mute/unmute 160
So in your ~/.xbindkeysrc, you can write a line like
-------<snip>----------
"amixer sset PCM +1"
m:0x0 + c:176
-------<unsnip>--------
and change your command and keycode appropriately. Lastly you
need to start xbindkeys. I usually have it start in my ~/.xinitrc
before the WM. But you can also just add it to the list of
programs automatically run by your WM on startup.
2) I think this way is probably better, but the last I tried I
couldn't get it to play well with e16, which is why I mention the
previous method. This method works with at least fvwm, and
probably most other WMs.
emerge xmodmap (if it is not installed already)
add the following lines to ~/.xmodmaprc
---------<snip>-----------
keycode 174 = XF86AudioLowerVolume
keycode 176 = XF86AudioRaiseVolume
keycode 160 = XF86AudioMute
--------<unsnip>----------
and make sure to start xmodmap when you start your X (again,
either by starting xmodmap in ~/.xinitrc or in your WM).
I believe some modern WMs will automagically tie the XF86Audio*
keys to appropriate mixer commands to raise or lower volume. If
not (as in the case of fvwm), you need to edit the keybinding for
those keys, and how to do this depends on your Window Manager of
choice.
