I have an old PC running Ubuntu 20.04.1 with no sound through the headphones. I'm not sure if there's a problem with the speaker output because I currently don't have working speakers to test it.
I've tried these commands:
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
alsamixer
sudo alsa force-reload
pulseaudio -k && pulseaudio -D
alsactl restore
sudo apt remove --purge alsa-base pulseaudio
sudo apt autoremove
sudo apt install alsa-base pulseaudio

-- UPDATE -- I upgraded to 22.04 and applied all updates
In Settings/Sound/Output/Output Device the only item available was "Dummy Output"
I followed the directions given here: No sound output devices listed after upgrade from 21.10 to 22.04
and ran these commands:
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager
Settings/Sound/Output/Output Device was updated correctly, but even with "Headphones - Built-in Audio" selected there's no sound.
Next, I ran these commands:
pulseaudio --kill && pulseaudio --start
sudo alsa force-reload
sudo alsactl restore
without success.
