I don't have this particular bug, but I guess that it is related to
pulseaudio trying to save and restore the volume of the soundcard between
sessions. Can you try commenting out the relevant lines in the file
"/etc/pulse/default.pa" (or "~/.pulse/default.pa" if it exist) and
"/etc/pulse/system.pa". The relevant lines are the ones just after the

    ### Automatically restore the volume of streams and devices

Maybe only one of them is faulty (I bet on "module-card-restore"), but you
may start removing all of them and see whether it helps.
