I've read through this thread with interest. I have an HP Compaq nx9110 with volume control buttons that have never worked for me. I switched the keyboard layout to "Laptop/notebook (eg Armada, Evo) Laptop Keyboard". Now the buttons act like they are doing something, meaning if I hit mute it says Mute On, but the the sound is not muted. Same results with up and down on the volume. I now also have kmix load in the task tray. I'm using alsa on this system, is that why the keys do not have any affect? How do I get them to actually control the volume/work with alsa? Any suggestions appreciated. James
