Public bug reported: After update my Dell Inspiron 5490 from Ubuntu 18.04 to 20.04 system see only "Dummy Sound".
I updated kernel to 5.6.13-050613-lowlatency, reinstall pulseaudio, add "options snd-hda-intel dmic_detect=0" to /etc/modprobe.d/alsa-base.con, add "blacklist snd_soc_skl" to /etc/modprobe.d/blacklist.conf. I applied the solution from this source: https://bugs.launchpad.net/ubuntu/+source /alsa-driver/+bug/1876238. I still have this problem.
