[HELP] switch user get slow and unresponsive

view story

http://chakra-project.org – I'm suspecting that this has some related to pulseaudio or the sound system.When the new session starts, from the "switch user" process, there is no start up sound. It seams that at the time that KDE will try to play the sound, than it can't and everything goes kind of freeze.But if i start KDE first with the new user, the sond plays and everything works great.
