I'm trying to start the unity environment from slim display manager, everything goes fine, except by the sound that don't work, the device just dont appear in the device list

I already changed the slim config file to start with this code below, but it didnt solve the problem....

login_cmd exec ck-launch-session dbus-launch /bin/bash -login /etc/X11/Xsession %session

I believe the it is related with some thing that the gdm/lighdm start with the session and slim dont do that

When I use the lighdm or gdm to start the environment everything works fine
