alsa-ucm-conf (1.2.2-1ubuntu0.5) focal; urgency=medium
* d/p/0001-sof-hda-dsp-add-initial-kcontrol-values.patch
* d/p/0002-sof-hda-dsp-make-the-boot-init-optional-for-all-cont.patch

* d/p/0004-sof-hda-dsp-Increase-the-speaker-output-volume-in-th.patch
Unmute the master playback switch and increase the init output volume,
otherwise, the playback will be muted after freshly install the OS if
the machine uses ucm to configure the audio mixers, and the init playback
output volume is too low after freshly install the OS.
