### Audio Volume hotkeys

If you are using LXDE, the following steps will get your Audio Volume hotkeys Fn-Right and Fn-Left as well as Fn-F6 to work.

First, you have to make sure that alsa is configured correctly. You can configure alsa using

    # alsaconfig

Executing

    # alsamixer

you can adjust the volumes to a convenient setting. Then, adding

    @ alsa

to the DAEMONS section of your rc.conf, you can ensure that the values you just specified will be loaded on every startup. Finally, paste the following lines into the <keyboard>-section of your ~/.config/openbox/lxde-rc.xml file.

     <!-- Keybindings for audio volume control -->
        <keybind key="XF86AudioRaiseVolume">
          <action name="Execute">
            <command>amixer -q set PCM 2+ unmute</command>
          </action>
        </keybind>
        <keybind key="XF86AudioLowerVolume">
          <action name="Execute">
            <command>amixer -q set PCM 2- unmute</command>
          </action>
        </keybind><keybind key="XF86AudioMute">
          <action name="Execute">
            <command>amixer -q set Master toggle</command>
          </action>
        </keybind>
