$ echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
$ echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
$ echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf

not work

attempt 5: reselect the older kernel

not work

attempt 6: boot in Windows

interestingly, also no sound, and then follow the instruction to track the sound issue, then it suggested rebooting.

Note: it froze after rebooting, so just power off.

the sound issue is solved, and after booting into Ubuntu, the sound resumes.
