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
dmesg output:
[   25.417568] ALSA hda_codec.c:4633: autoconfig: line_outs=2

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:

0x0f 0x411111f0
0x10 0xb7031110
0x11 0x411111f0
0x12 0x02a11820
0x13 0xb7831121
0x14 0x0221101f
0x15 0x21011010
0x16 0x411111f0
0x17 0xb7931122
0x18 0x2145111e
0x19 0x411111f0

Does each of the hex values on the left refer to a node? If so, where
are those before 0xf and after 0x19?
