This is the standard across all elements implementing the volume property, and makes sense as it maps more naturally to underlying APIs and hardware. The idea of a cubic mapping (or any other natural-sounding mapping) should be left as an application decision and does not belong in middleware layers. To make things easier for GStreamer-based applications, there is a GstStreamVolume interface which can do a cubic mapping if requested. You'll notice that Rhythmbox actually does this already: http://git.gnome.org/browse/rhythmbox/tree/backends/gstreamer/rb-player-gst.c#n311 -- Arun
