HP Ultraslim Dock Linux Audio [Permalink]

I've had an issue for some years regarding the line in and out sockets on my HP dock, where Linux hasn't been able to detect them and so I've been using the headphone jack on the laptop instead.
I finally worked this out so I'm documenting it for future me and also anyone else.
The answer is in these three lines of modprobe config. I don't know what they do, as with all things surrounding sound in Linux, it's fairly magic. YMMV.
options snd_hda_intel model=hp-dock
options snd_hda_intel beep_mode=0
options snd_hda_intel enable_msi=1
