I've tried to edit the configuration file in ~/.config/openbox/lxde-rc.xml however the changes don't take effect, i still can't use the keys.

The LXDE wiki shows that after finding that my keyboard sends the correct standardized keyboard events i should go and edit the file to my liking, the keyboard does send the correct events and the keys are properly identified yet nothing happens.

Since LXDE doesn't come with a sound preferences option i have installed xfce4-mixer. I too have a netbook running Lubuntu and its media keys are working fine, i don't know if what i installed has had something to do here?.

I also installed xfce4-volumed volume keys daemon from synaptic but to no avail, still nothing.

How can i make the multimedia keys of my keyboard ( Microsoft Wireless Keyboard 1000) work in LXDE with xfce4-mixer

Edit: Here is my lxde-rc.xml file

I've commented the line OnlyShowIn=XFCE: in /etc/xdg/autostart/xfce4-volumed.desktop and now i get a notification when pressing the Volume keys however it doesn't have any effect on the audio output. The Play/Pause, Stop, etc. Keys still don't work.

I also tried to use the commands my XML file has, i.e. amixer sset Master 3%+ and i get this:

  Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum
  Playback channels: Mono
  Limits: Playback 0 - 64
  Mono: Playback 5 [8%] [-59.00dB] [on]

Using the command again raises this value Mono: Playback 5 [8%] [-59.00dB] [on] to Mono: Playback 7 [11%] [-57.00dB] [on] but no audible effect is noticed.

On a different note I believe xfce4-volumed is XFCE only startup job. Make sure its running in lxde as well. – sagarchalise Dec 1 '11 at 7:21
basically comment the the line showonlyin: XFCE in /etc/xdg/autstart/xfce4-volumed.desktop. I think ps aux | grep xfce4-volumed would say if process is running or not. – sagarchalise Dec 1 '11 at 7:34
@fossfreedom Done editing the question, i do have pulseaudio installed, killing it causes the volume to drop in dB even when the volume control slider is at the max. – Uri Herrera Dec 1 '11 at 23:21
Uri - just confirming what I think you said - killing pulseaudio and then running the amixer commands manually changes the volume correctly. Having pulseaudio and running the amixer commands manually does not change the volume - hence it is pulseaudio that is clashing with LXDE ALSA Audio. What happens if you just uninstall pulseaudio and reboot. – fossfreedom Dec 2 '11 at 10:45
Killing pulseaudio makes the volume sort of drop in dB, and then if i use the amixer commands to raise the volume they don't do anything. But i will uninstall it and see what happens. – Uri Herrera Dec 2 '11 at 15:11

I have reinstalled the whole OS due another inconvenience, now i'm using XFCE instead of LXDE
