Hi, I have a laptop with a physical volume knob -- it's a little wheel sitting on the side of the computer. Now my question is: How do I make it actually adjust the sound volume? Because it doesn't -- when I turn it, nothing happens. With some investigation, I find that turning the wheel generates some events on /dev/input/event1 when I move it. This seems to be coming from the keyboard. I: Bus=0011 Vendor=0001 Product=0001 Version=ab41 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/class/input/input1 U: Uniq= H: Handlers=kbd event1 B: EV=120013 B: KEY=4 2000000 3803078 f800d001 feffffdf ffefffff ffffffff fffffffe B: MSC=10 B: LED=7 So it seems that the wheel is not hard-wired to the sound card or speakers at all. How would I go about to making it change the sound volume? I don't even know where to begin. The keyboard/input driver? Register an event listener somewhere in ALSA? Or is this a job for user-space alone? I would be grateful for a helping hand! Thanks.
