I have a similar issue, but it fixed itself after I downgraded and
upgraded again.

With pa 9.0:
$ pacmd list-sinks | grep name:
        name: <alsa_output.pci-0000_00_1b.0.analog-stereo>

With pa 8.0:
$ pacmd list-sinks | grep name:
        name: <alsa_output.pci-0000_00_03.0.hdmi-stereo>
        name: <alsa_output.pci-0000_00_1b.0.analog-stereo>

More than that, the pacmd list-sinks output didn't have any "ports" in
the output with pa 9.0, which prevented me from switching to headset
instead of speakers.

Now, the interesting thing is that I downgraded to 8.0, killed the
pulseaudio daemon(s), tested that it worked as before the upgrade,
then went back to 9.0, killed the pulseaudio daemon again, and it still
worked. This would suggest some sort of race condition at boot time.

I'm not in a position where I can easily reboot to test the theory.
