Another bit of data. I set "autospawn = no" in my ~/.pulse/client.conf, killed the current pulseaudio process and started "pulseaudio -vvvvv". I did this for both users.
Unfortunately, I didn't find anything interesting. pulseaudio logs something like the follow regardless of whether the sound ends up working or not. This is consistent with fuser showing that the user on the active console has the pcm device open whether or not the sound is working. The follow is what pulse audio prints out between when I switch away from a user and when I switch back the user (either directly or via another console to make the sound work). ...
