The patch introduces D-Bus support in amixer. With --dbus option given amixer works continiously (like with the --stdin) waiting for org.freedesktop.Hal.Device.Condition with the first argument "ButtonPressed" and the second being one of: "volume-up", "volume-down" and "mute". These are emmited by the HAL input helper. A single amixer process can controll one mixer item. There are options to choose a specific item to controll, an input device to listen and a single adjustment step size.

Thanks for the patch.
The approach is interesting, but I'm not sure whether we should put all into amixer in this way since we don't want extra library dependency. (Note: amixer could be used in initrd.) I think it's better to split the code and make it as an individual daemon instead of additional options of amixer.
No worries ;) there is --with(out)--dbus option for configure to disable all this code which is enough for initrd because most often (AFAIK) initrd binaries are not the same that in the live system.
