Hi all,
I resolved my problem thanks to this solution:
https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-
in.html .
I followed these instructions:
1. Edit /etc/modprobe.d/alsa-base.conf as root and add options snd-hda-intel
dmic_detect=0
2. Edit /etc/modprobe.d/blacklist.conf as root and add blacklist snd_soc_skl at
the end of the file
3. After making these changes, reboot your system.
Tested with 5.3.0-45-generic kernel.

Bug description:
Hi all,
After an update of Ubuntu kernel (version 5.3.0-42-generic) I can't
have sound any more. No soundcards are detected any I have a "dummy
output" in the sound pannel in settings. Furthermore I can't resume
from sleep anymore.
