The problem when you use a gstreamer->tinycompress path is that you have 
no hooks for volume control and audio policy/routing. It'll remain a 
test toy. If you want integration with a better user-friendly support, 
the right answer is to go through PulseAudio and write a compressed sink 
within pulseaudio. See the LPC slides from 2010 or 2011 that describe 
the solution. And Arun can help you with that, he wrote the 
gstreamer/pulseaudio interface :-)
