When I want to debug pulse I do

echo "autospawn = no" > ~/.pulse/client.conf

kill PA and run it from command line with -v option you can also
use --log-level (man pulseaudio)

perhaps you can see what is the problem there. If not it might be dbus issue
with permissions - check the dbus settings

Also some times it helps to remove the ~/.pulse directory and restart
