The solution below solved the problem at least in one case:
#2 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):
Code: Select all
echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
You can do this with a single command, by using (run this command only once):
Code: Select all
echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf
