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?
Thanks Baek
