My guess is that both the laptop volume control and Xmod send keyboard events. If that is correct, then you can check what keycodes they send with xev. Run xev in a terminal, and then make sure that the window that pops up has focus and that you can still see the terminal output. Pressing keys should cause KeyPress and and KeyRelease events. Check the keycode values of the volume controls; if they have the same keycode, I think there's no way you could control different things with the laptop controls and the Xmod controls. If they do send keyboard events and they have different keycodes, I think you have hope, but I don't know how to do the configuration... > 2) When I control the volume of the Xmod, the volume jumps up and down > rather erratically, and loses synch between the right and left > channel.

If you control the volume with "alsamixer -c1" (I'm assuming the card has index 1, you can check that with "cat /proc/asound/cards"), and it doesn't work any better, then I think you can't do anything about this problem. If it does work better, then again you probably can do something, but I don't know what ;) -- Tanu Kaskinen
