XVolume is a simple Xlib volume control that mimics the traditional OSD (on screen display) controls found in various appliances. It is intended to be launched by a shortcut key (eg. one of the "Internet" buttons on your keyboard) and one can then directly adjust the volume by user-defined keys. It was inspired by a similar feature in the Windows driver for a Logitech keyboard. Xvolume is highly configurable and can be tailored for a perfect fit with your window manager.
