1) What I already tried to do
All the instructions in: https://support.system76.com/articles/audio/ , specifically:
i. reinstalling pipewire and deleting configurations:
systemctl --user restart wireplumber pipewire pipewire-pulse
rm -r ~/.config/pulse/
rm -r ~/.local/state/wireplumber/
iii. snh_hda_intel specific bug fix
echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf
(reboot)
