With the updated pavucontrol, what happens if you change the balanced volume of your channels (lets say, you turn the front speakers down a bit to 80% and leave the rest at 100%), and open a new audio application or change the volume of a running app? Does that reset your channel volumes to the same level? It did with the Karmic version I ran, which happens to be the same version as in that PPA.
