PulseAudio successfully opens the "front" device, which it shouldn't be able to do. Now that I look at HdmiLpeAudio.conf, I see that it defines the "front" and the various "surround" devices, which confuses pulseaudio, because pulseaudio expects those to be analog devices.
I attached no-analog.patch. Look at the removed lines - if you remove those from your HdmiLpeAudio.conf, does pulseaudio work then? If not, the verbose log will again be useful.
