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

Hi, I have the following hardware:

~> cat /proc/asound/cards 0 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xf7080000 irq 90 1 [Generic ]: HDA-Intel - HD-Audio Generic HDAudio-Gigabyte-ALC1220DualCodecs

and I'm running:

~> cat /etc/os-release NAME="openSUSE Tumbleweed" # VERSION="20200228" ID="opensuse-tumbleweed" ID_LIKE="opensuse suse" VERSION_ID="20200228" PRETTY_NAME="openSUSE Tumbleweed" ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:tumbleweed:20200228" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://www.opensuse.org/" LOGO="distributor-logo"

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

~> pulseaudio W: [pulseaudio] pid.c: Stale PID file, overwriting. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Mic1, assuming stereo duplex. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Mic2, assuming stereo duplex. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Line2, assuming stereo duplex. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Headphones, assuming stereo duplex. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Line1, assuming stereo duplex. W: [pulseaudio] alsa-ucm.c: UCM file does not specify 'PlaybackChannels' or 'CaptureChannels'for device Speaker, assuming stereo duplex. E: [pulseaudio] alsa-ucm.c: Assertion 'jack' failed at modules/alsa/alsa-ucm.c:2158, function device_add_hw_mute_jack(). Aborting. Aborted (core dumped)

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/...) and then use the version of HiFi-dual.conf before it was moved, then PulseAudio starts normally and I have sound.
