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 @DEFAULT_SINK@ +1000 (up in % or db ending), pactl set-sink-volume @DEFAULT_SINK@ -1000 (lover), mute = pactl set-sink-mute @DEFAULT_SINK@ toggle
Here is the modification of my ~/.config/openbox/lxde-rc.xlm
