I don't think, you need an extra daemon like lineak for this functionality.
Have you tried to switch to a different keyboard layout in System Settings? 
Maybe one of the multimedia keyboards contains your hotkey setup.

Otherwise... have you tried, if your hotkeys are already recognized by the 
X-server ("xev"), and if not make them known to the X-server by e. g.
  xmodmap -e "keycode 160 = XF86AudioMute"
  xmodmap -e "keycode 176 = XF86AudioLowerVolume"
  xmodmap -e "keycode 174 = XF86AudioRaiseVolume"
  xmodmap -e "keycode 178 = XF86HomePage"
  xmodmap -e "keycode 236 = XF86Mail"
(your keycodes may differ, you should probably be able to find out in dmesg).
This works nicely for me and also has a nice OSD reminder.
