Symptom: No front/rear sound problems under Linux OS

Solution 1:

From: https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
"Fix PCI/internal sound card not detected (dummy output) with Ubuntu kernel 5.3.0-41 and -42 in Ubuntu 19.10 / 18.04"

The solution for this "dummy output" regression is to:

1. Edit /etc/modprobe.d/alsa-base.conf as root and add options snd-hda-intel dmic_detect=0 at the end of this file. You can do this with a single command, by using (run this command only once):

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

2. Edit /etc/modprobe.d/blacklist.conf as root and add blacklist snd_soc_skl at the end of the file. You can do this with a single command, by using (run this command only once):

echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf

3. After making these changes, reboot your system.

Solution 2:

In addition there was another recommendation, that solved this problem in another similar case:
