解決方法

You will need to add an option on GRUB.

To edit grub options:

sudo nano /etc/default/grub

Find GRUB_CMDLINE_LINUX_DEFAULT and add snd_hda_intel.dmic_detect=0 to the end of it. It will look something like this:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd_hda_intel.dmic_detect=0"

Then rebuild grub menu:

sudo grub-mkconfig -o /boot/grub/grub.cfg

After you reboot the system the device should work.
