There is a chance that when your system starts, some sort of system 
device, using ALSA problably is getting access to the audio hardware and 
when pulse starts up, it cannot get control of it. Pulse needs to get 
control of the hardware during startup to initialise itself. It will 
release it again shortly afterwards to let pure alsa apps function as 
normal (albeit blocking pluse output).

Generally it's recommeneded to route alsa's "default" output to 
pulseaudio and thus everything works nicely together.

Anyway, to help debug your problem, once you've logged in, kill the 
running pulseaudio process (pulseaudio -k) and start a new one with 
pulseaudio -vvv and paste the output to a pastebin somewhere and put the 
link in this mail..

You can also join us on IRC over at #pulseaudio on Freenode which may be 
a little more interactive :)

Take care
