[SOLVED] Lenovo Thinkpad X1 Yoga: soundcard undected on kernel 5.5

After updating to kernel 5.5.x the system stopped recognising the sound card (I use pulseaudio with the pulse-alsa plugin). Using the lts kernel solves the problem. Not sure if this post belongs here or to the Kernel and driver section.

Here's the output of aplay -l on kernel 5.4.19:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC285 Analog [ALC285 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Here's the output of aplay -l on kernel 5.5.3:

no sound card available

Stopping the pulseaudio daemon does not change the situation.

On both kernels the output of lspci | grep -i audio is the same and it is the following

00:1f.3 Audio device: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 11)

If you have any idea or other possible things I can check please feel free to share.

Likely the dmic detect bug. Try creating a modprobe file like e.g. /etc/modprobe.d/disable_dmic.conf

options snd_hda_intel dmic_detect=0

and reboot

Yes it was. Adding such file to the modprobe.d folder solved the problem. Marking the topic as solved.
