Pulseaudio (and ALSA) stopped detecting sound card

Pulseaudio stopped detecting my analog sound card a few days ago after a system update. I've got a laptop with an HDMI sound card (Broadwell-U Audio Controller) and an analog sound card (Wildcat Point-LP High Definition Audio Controller).

/proc/asound/cards:

 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf731c000 irq 53

hwinfo --sound:
