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
