Lxde media keys activated
#1
Did find that the media keys were missing so I did a little bit of duckduckgo to find out.    You have to add them in to ~/.config/openbox/lxde-rc.xlm under the <keyboard> section.  You find out the <keybind key=""> with the command line program xev.  Then you can configure the keys <command> with amixer (better) and pactl. 

The alsamixer commands are; XF86AudioMute = amixer -D pulse sset Master toggle, XF86AudioLowerVolume = amixer -D pulse sset Master 10%-, XF86AudioRaiseVolume = amixer -D pulse sset Master 10%+

Pavucontrole = pactl set-sink-volume @[email protected] +1000 (up in % or db ending), pactl set-sink-volume @[email protected] -1000 (lover),  mute = pactl set-sink-mute @[email protected] toggle

Here is the modification of my ~/.config/openbox/lxde-rc.xlm
