alsa-project/alsa-ucm-conf issue #61 was opened from J-Bu:

Hi,

since upgrading to alsa-ucm 1.2.4 I only have a "Dummy Device" instead of the internal speaker. When using alsa-ucm 1.2.3 all is fine.  I'm not quite sure if this is a pulseaudio or alsa issue maybe you can guide me in the right direction
