- Install pulseaudio and pavucontrol to get the sound working.
sudo apt-get install pulseaudio pavucontrol
- Restart your computer. The sound should be up and working fine and there would be volume applet in LxPanel. Now, you may notice that the volume button in the keyboard isn’t working. That’s fine. You can make it work rather easily. You see, LXDE uses openbox as the window manager. Openbox is very flexible and fully customizable. Open the rc.xml file and replace the following code with their counterparts present in the rc.xml file. Don’t worry, it’s safe.
- Open rc.xml file with the following:
- Now search for ‘Keybinding for Volume management’. There you would find the key-bindings for volume raise and lower as below with slightly different key-bindings. Just replace those two (only those two) with the key-bindings below.
<command>amixer -q -D pulse sset Master 3%+ unmute</command>
<command>amixer -q -D pulse sset Master 3%- unmute</command>
- Reboot your computer and everything should be working fine.
