This solution not works in Kubuntu. I select PCM as the principal mixer 
channel but not works. However I select Mic as the principal channel 
kmix mute the mic channel when I press the mute button, but not with 
PCM. Now with the volume up and down button I configured a keyboard 
shortcut with kde and dcop, this works perfectly, except the mute 
action; kmix mute, but the speakers continue sound. ???
