OK, this produced some interesting behaviour, new alsa info at:
Headphone volume appears at node 0x8 and speakers at 0x9, however
there is no sound over the speakers now, possibly related to this

I've had a read through HD-Audio.txt and a quick look at the HD audio
spec from Intel. It isn't clear to me how the pin configs relate to
the way things are set up. The
/sys/class/sound/hwC0D0/init_pin_configs file looks like this:
Does each of the hex values on the left refer to a node? If so, where
are those before 0xf and after 0x19?
