** Description changed: [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 - Need the https://github.com/alsa-project/alsa-ucm-conf/pull/465/commits/633a01b1e538ee9a577185f067bf2ca63696ada5 which is not yet landed upstream officially to fix the routing for internal speaker [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 low risk of regression + 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.
