On Linux systems, a connected numeric keyboard or an infrared remote control can be used for controlling playback for the Klipspringer hub, as a complement to the web interface. Note, however, that this aspect of the system of the system is not yet streamlined to be easily configurable.
Remote
The device of the remote control, something like /dev/input/event3 (most likely with a different number than 3 on your system), is specified with the -remote option.
Keypress actions may become configurable in future versions, but currently they are hard coded in to do useful things for a particular CD player remote:
- Play/pause, stop, next, previous, fast forward, and rewind: these do what they would do on a CD player.
- Channel up and down: move backwards and forwards in the playing history for the track player. History items correspond to collections of audio files which may be albums or playlists.
- Program: moves the current history item to the front of the history.
- Clear: removes the current item from the history.
- Repeat: restarts the current item.
- Shuffle: switches source group.
Note that if you have Gnome or some other window system running, this may react to remote keypresses in a way that conflicts with the Klipspringer hub. There is a description of how this may be turned off near the end of the blog entry about using a CD drive. Some further details about how the remote control works and how it can be configured can be found in the blog entry about Linux device input.
Numeric keyboard
The device of a connected numeric keypad is specified with the -numpad option. How this controls playback may also be made configurable in the future. Currently, the main use is that the number keys choose between sources that are specified to belong to the radio group.
