alsa-project/alsa-ucm-conf issue #14 was edited from JeremyFiggins:

Hi, I have the following hardware:

> ~> cat /proc/asound/cards
>  0 [NVidia         ]: HDA-Intel - HDA NVidia

>                       HDAudio-Gigabyte-ALC1220DualCodecs

and I'm running:

Audio was working until a recent update. Now, I have no audio and when starting PulseAudio, I get:

I tracked it down to /usr/share/alsa/ucm2/HDA-Intel/HiFi-dual.conf. If I revert the two commits here (https://github.com/alsa-project/alsa-ucm-conf/commits/master/ucm2/HDA-Intel/HiFi-dual.conf) and then use the version of HiFi-dual.conf before it was moved, then PulseAudio starts normally and I have sound.
