Hi, This isn't really a bug report but I need somewhere to dump this so I don't forget :) This happened with a fake null sink (pactl load-module module-null-sink sink_name="fake51" channels=6 channel_map="front-left,front-right,center,rear-left,rear-right,lfe"), pavucontrol, split the channels and then update the volume of one of the channels. I'll try and reproduce properly via a debugger at some point soon, but for the sake of documenting it happened, here is the log :p May 21 23:09:23 jimmy pulseaudio[4751]: module-stream-restore.c: Restoring volume for sink input sink-input-by-media-role:event.
