Yes, it seems that your changes doesn't fix this bug. But maybe you have some ideas where or what we need to fix?

I tried to install it, but still doesn't work.

I started to think that problem could be with greeter, but I guess I was wrong. Tried two greeters:
* unity-greeter for both seats
* lightdm-greeter for both seats
* unity-greeter for seat0 and lightdm-greeter for seat1

I was able to loggin in both seats two times today, but I have no idea what could caused that - mostly it doesn't work. When I was logged in both seats everything was working. First time I was able to use sound on both seats without starting pulseaudio systemwide.
