My Nvidia device has now moved from Card 2 to Card 1 and the system settings->sounds dialog now shows a HDMI/displayport 2 device.
I no longer get random crashes of the kernel from snd_hda_intel module.
Pulse audio no longer reports that it cannot initialise the device. Current error report from pulseaudio is:

Which does not look serious.
However sound still does not work.
