[pulseaudio-discuss] volume ramping

What is the proper way to do volume ramping in pulse audio to avoid clicking
when changed the volume? I wrote a module to callback and change the volume
in small incremental steps, but it seems that pulse seems to apply the
volume changes on the audio buffer as a whole. Does pulseaudio take a
volume command, and then process the one audio buffer with that set volume?
I'm using a buffer size of 4096 at 44100Hz, so it is about 10mS. So how
would I go about ramping the volume, in say about 15 mS?
