Bug description:
After update my 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.
Audio: Device-1: Intel driver: sof-audio-pci
Sound Server: ALSA v: k5.6.13-050613-lowlatency
