I noticed a problem with my keyboards mute/unmute button. It seems that it only mutes, but the solution is simple.
Do the following, edit the .config/openbox/lubuntu-rc.xml with nano.
sudo nano .config/openbox/lubuntu-rc.xml
scroll down untill you see this
<!-- Keybinding for Volume management --> <keybind key="XF86AudioRaiseVolume"> <action name="Execute"> <command>amixer -q sset Master 3%+ unmute</command> </action> </keybind> <keybind key="XF86AudioLowerVolume"> <action name="Execute"> <command>amixer -q sset Master 3%- unmute</command> </action> </keybind> <keybind key="XF86AudioMute"> <action name="Execute"> <command>amixer -q sset Master toggle</command> </action> </keybind>
and type in the following: -D pulse after the -q so it looks like this
<!-- Keybinding for Volume management --> <keybind key="XF86AudioRaiseVolume"> <action name="Execute"> <command>amixer -q -D pulse sset Master 3%+ unmute</command> </action> </keybind> <keybind key="XF86AudioLowerVolume"> <action name="Execute"> <command>amixer -q -D pulse sset Master 3%- unmute</command> </action> </keybind> <keybind key="XF86AudioMute"> <action name="Execute"> <command>amixer -q -D pulse sset Master toggle</command> </action> </keybind> reboot and done!
