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 :-)
