I've had some trouble with sound for a few weeks already, it just doesn't produce any output on my system. I've tried submitting a bug report, but there is no answer from launchpad, the bug importance is undecided and it is not assigned to anyone. I have used Ubuntu 18.04 before and had no trouble with sound.
So, I've decided to reinstall Ubuntu in hope that the issue gets fixed, but that did not happen. I would really want to solve the problem, but I don't know how. I've looked up a lot of things and tried them, but nothing works...
Things I've tried:
options snd-hda-intel dmic_detect=0 to /etc/modprobe.d/alsa-base.confblacklist snd_soc_skl to /etc/modprobe.d/blacklist.confI kindly ask for help.
I am posting relevant outputs below:

But there is no sound still.
For Pulseaudio
Ensure the /etc/libao.conf defaults to pulseaudio
default_driver=pulse
[or edit or create a local .libao (note the dot as the first character) file in your home directory (this will take precedence over the /etc/libao.conf file which is system wide)]
Ensure that the pulseaudio daemon is enabled
systemctl --user enable pulseaudio.service pulseaudio.socket
The check pulse audio:
systemctl --user status pulseaudio
Edit
It's been report that speech-dispatcher sometimes breaks audio
try editing /etc/default/speech-dispatcher
change RUN=yes to RUN=no
or
if you don't use it, remove it.
Also see: https://askubuntu.com/questions/1218058/ubuntu-19-10-audio-driver-issue
which resolves a similar issue by editing /etc/modprobe.d/alsa-base.conf
namely adding
options snd-hda-intel dmic_detect=0
