Audio card not detected by Alsa (but Kernel does)

On Ubuntu 16.04, I'm trying to play sounds from this card (integrated 3.5mm analog output):

$ lspci -nn | grep -i audio
00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-H HD Audio [8086:a170] (rev 31)

However, it appears ALSA is not able to detect it.

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

This is what alsamixer shows for this card: no audio controls for PCH audio card

However, from the followings, it appears the kernel is able to detect the card and the snd_hda_intel driver is assigned to it:

    $ lspci -v | grep -A7 -i "audio"
    00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)
    Subsystem: Intel Corporation Sunrise Point-H HD Audio
    Flags: bus master, fast devsel, latency 128, IRQ 133
    Memory at c1140000 (64-bit, non-prefetchable) [size=16K]
    Memory at c1130000 (64-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel

Also

    $ cat /proc/asound/cards
    0 [PCH            ]: HDA-Intel - HDA Intel PCH
    HDA Intel PCH at 0xc1140000 irq 133

I have two more identical machines with the same exact Kernel version and versions of alsa-base and alsa-tools. ALSA can correctly detect the PCH audio card on those. Any idea on how to solve ALSA interface with this card?

I found this but the answer doesn't seem to really answering the question (at least not the way I understand it). Also found this, but solution was not working for me.

Thank you in advance for any help.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
