Missing card/device (Intel HD audio)

A few months ago, aplay -l would show 2 cards each with 2 devices. Two were HDMI and the other two were PCH. Now aplay -l returns only HDMI:

card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

What happened to PCH? I miss having sound.

Also, here's the relevant line from lspci:

00:1b.0 Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller
