"!!ALSA Version
!!------------

Driver version: k5.4.0-110-generic
Library version: 1.0.16
Utilities version: 1.2.2"

Library version and utilities version should be identical.

Do you have all available updates correctly installed?

What output do you receive for the commands

sudo apt update
sudo apt full-upgrade

Hi Manfred

Thanks.

I do not get any errors and all packages are upto date. My inbuilt
webcam is also not working.

apt-cache policy libasound2

And another issue:
libkmod: ERROR ... /etc/modprobe.d/blacklist.conf line 53: ignoring bad line starting with 'snd_soc_skl'

What is the output of the command

cat -n /etc/modprobe.d/blacklist.conf

*$ apt-cache policy libasound2*

The wrong 'snd_soc_skl' entry mentioned in your logs is no shown in the blacklist.conf file (any more).
Did you already try correcting errors?

There is something wrong with your package management configuration.
You are running Ubuntu focal, but for the libasound2 package you only get the version for bionic.

What output do you receive for the following command:

find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;
