Bug description:
[SRU Justifications]
========== alsa-ucm-conf ==========
[Impact]
Audio output doesn't work on Dell Tarako platforms with Cirrus CS42L43
codec
[Fix]
This requires following conf file in alsa-ucm-conf package:
- /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
[Test Case]
1. Boot up the machine of Dell Tarako platform with CS42L43 codec
2. Verify the existence of /usr/share/alsa/ucm2/sof-soundwire/cs42l43-spk.conf
3. Verify firmware-sof version >= 2023.12.1-1ubuntu1.2 on Noble,
2024.06-1ubuntu1.1 on newer (with sof-lnl-cs42l43-l0.tplg)
4. Make sure the sof driver are loaded correctly. (tplg and Intel DSP FW are
ready)
5. Verify with checking the output of `amixer -c 0` command with valid
Digital Speaker `Simple mixer control 'cs42l43 Speaker Digital',0`.
[Where problems could occur]
It only affects the Dell Tarako platforms with the new CS42L43 codec w/o
other soundwire devices. Should be low risk of regression and only limited to
such platform.
