Ubuntu – Ubuntu no sound, dumthe output, and no sound card detected

This happened after I installed Skype on my Ubuntu 18.04.4 LTS. I found out that Skype had no sound so that I searched for the solution. Someone suggested installing pavucontrol

sudo apt install pavucontrol

After that, it did not solve my Skype problem and it caused my laptop to lose audio output.

I tried a bunch of solutions online, but none of them works. Here are the solutions that I already tried.

# solution 1
pulseaudio -k && sudo alsa force-reload

# then I did
pacmd list-cards

# which gives me
0 card(s) available.

# I also tried
aplay -l
aplay: device_list:270: no soundcards found...

#solution 2
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoremove

sudo killall pulseaudio
rm -rf ~/.config/pulse
pulseaudio -k

I tried these and restarted my laptop. But none of them works. My laptop is hp spectre x360. Any suggestions? Thanks a lot!

Updates

I ran the alsa-info script from here. And this is what I got:
