That's very weird.  I don't understand why it doesn't autostart.  You
should probably file a bug about this.

In the meantime try adding pulseaudio to your user-specific autostart
directory and see if that makes it go:
mkdir -p ~/.config/autostart
cp /etc/xdg/autostart/pulseaudio.desktop ~/.config/autostart/

For starters, both your regular audio and HDMI audio devices are
suspended.  That might be related to the fact that PulseAudio is
starting late; something else might be locking the ALSA device.  You
can try to un-suspend your audio devices by running:
pacmd suspend false

If that gives you some sort of error, you probably have to fix
pulseaudio autostarting first.

Now, lets forcibly play some sound through your HDMI audio.  If you
have amarok installed, this will work, or you can point it to any OGG
or WAV audio file (there are a bunch in /usr/share/sounds):
pacmd play-file /usr/share/kde4/apps/amarok/data/first_run_jingle.ogg 0

If that works, try playing some sound in a normal application and see
if your HDMI audio works then too.

If that doesn't work, change the 0 at the end of that command to a 1
and run it again.  If sound comes out of your laptop's internal
speakers, PulseAudio is working and it's just an HDMI problem.  If no
sound comes out of them, something is wrong with PulseAudio in general
(or possibly the file you tried to play doesn't exist or work).  If
you haven't sorted out the autostarting yet, that's probably related.
