Upgrading to Ubuntu 20 has caused all audio output except HDMI to disappear

Question

I use my 3.5mm output jack from a desktop pc to a receiver for audio. After upgrading to Ubuntu 20, the only audio output that shows up any more is HDMI. I get audio popping and crackling from the HDMI, which is why I use the 3.5 mm jack instead.

Does anyone know why this broke, and how to fix it?

Welcome to Askubuntu!

Have you tried to install pavucontrol?

sudo apt install pavucontrol

+Check so that nothing is muted (in pavucontrol)

Edit: Glad it worked for you:

From the first link provided:

Found here: Ubuntu no sound, dummy output, and no sound card detected

Open /etc/modprobe.d/alsa-base.conf and add the following line at the end:
options snd-hda-intel dmic_detect=0
Then:
pulseaudio -k && sudo alsa force-reload
You will hear the sound.
sudo apt-get remove timidity
sudo reboot

I had to do all 3 steps. Open /etc/modprobe.d/alsa-base.conf and add the following line at the end:
options snd-hda-intel dmic_detect=0 Then:

pulseaudio -k && sudo alsa force-reload

remove timidity:

@Zaichik Oh - thanks for pointing it out; what exact steps? I'm a bit confused; I thought you meant only the 1 accepted answer on the link; ? :) – William Martens Oct 11 '20 at 14:57

I had to modify the alsa-base.conf, did the alsa reboot, and remove timidity software from apt. Just doing the alsa reboot did not work. I also rebooted the OS after doing this. – Zaichik Oct 11 '20 at 14:58
@Zaichik Just to confirm; is it correct now? – William Martens Oct 11 '20 at 15:03
