Public bug reported:
A very brief test on a Lenovo S790 shows that the alsa-ucm-conf package
does not support the cs42l43-cs35l56-bridge configuration that was
merged up stream in July 2024 and included in the November 2024 1.2.13
release tagging.
This configuration is used in a number of products from Dell and Lenovo.
Description: Ubuntu 25.10
Release: 25.10
Looking at the plucky release notes I can see
alsa-ucm-conf (1.2.12-1ubuntu1.2) plucky; urgency=medium
* Import patches that have already been applied to noble and oracular,
but not yet to plucky. This and previous uploads are dependent on
these patches.

- d/p/0002-sof-soundwire-Add-support-for-cs42l43-cs35l56-bridge.patch
- d/p/0001-sof-soundwire-Change-map-control-names-to-make-them-.patch
- d/p/0002-sof-soundwire-Add-sequence-for-controlling-Mic-Mute-.patch
- d/p/0004-rt722-add-mic-led-support.patch
Which probably introduced this support into the Ubuntu Package.
