My guess, your keys are playing nice with the box but your config is not.

This is how it pretty much should look like in
~/.config/openbox/lubuntu-rc.xml (I hope I remeber the file name
correct, should be obvious at least.)

Using amixer here, I am not sure about lubuntu defaults and so on -
hopefully others might be able to help on that part.

    <!-- local volume control with normal buttons on keyboard -->
    <keybind key="XF86AudioLowerVolume">
      <action name="Execute">
        <startupnotify>
          <enabled>true</enabled>
          <name>amixer</name>
        </startupnotify>
        <command>amixer -c 0 set Master 3- unmute</command>
      </action>
    </keybind>
    <keybind key="XF86AudioRaiseVolume">
      <action name="Execute">
        <startupnotify>
          <enabled>true</enabled>
          <name>amixer</name>
        </startupnotify>
        <command>amixer -c 0 set Master 3+ unmute</command>
      </action>
    </keybind>
    <keybind key="XF86AudioMute">
      <action name="Execute">
        <startupnotify>
          <enabled>true</enabled>
          <name>amixer</name>
        </startupnotify>
        <command>amixer set Master toggle</command>
      </action>
    </keybind>


(this is also covered in the upstream FAQ if not in the Ubuntu FAQ...
<http://wiki.lxde.org/en/FAQ#How_do_I_make_my_keyboard_volume_buttons_work.3F>)



A example of how you can do something similar for a remote station could
look like this:

    <!-- volume control at remote station with "music" button and
"play/pause" button -->
    <keybind key="XF86Tools">
      <action name="Execute">
        <startupnotify>
          <enabled>true</enabled>
          <name>amixer</name>
        </startupnotify>
        <command>ssh -i /home/brother/.ssh/id_rsa_music music at music
"amixer -c 0 set Master 5- unmute"</command>
      </action>
    </keybind>

I control the volume at the remote music box at work using two other
media buttons (XF86Tools and XF86AudioPlay as identified by xev =))
