I did a backport for alsa-ucm-conf in noble and put it to my ppa
ppa:kchsieh/verification. Here is my list:
alsa-ucm-conf (1.2.10-1ubuntu6~oem10) noble; urgency=medium
* Support cs42l43 speaker with cs35l56 amplifier (LP: #2055375)
- d/p/0001-sof-soundwire-Use-one-file-for-speaker-codec-initial.patch
- d/p/0001-sof-soundwire-fix-rt1318-config-typo-in-rt1318spk-ma.patch
- d/p/0001-sof-soundwire-fix-rt1318-config-copy-n-paste-error-i.patch
- d/p/0001-sof-soundwire-rt1308-Fix-single-amp-configuration.patch
- d/p/0001-sof-soundwire-rt1316-rt1318-fix-channel-selection-fo.patch
- d/p/0001-sof-soundwire-Add-missing-match-for-cs42l43-speakers.patch
- d/p/0001-sof-soundwire-Add-basic-support-for-basic-cs35l56-co.patch
- d/p/0001-sof-soundwire-Add-basic-support-for-cs42l43.patch
- d/p/0001-sof-soundwire-Add-missing-match-for-cs42l43-speakers.patch
- 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
I think we need to backport them all for not breaking
rt1308/rt1316/rt1318.

Bug description:
[SRU Justifications]
========== firmware-sof ==========
[Impact]
Audio doesn't work on Dell new XPS laptops on Intel MTL platforms.
[Fix]
Kernel driver, ALSA ucm, and firmware fixes are required. For
firmware-sof, it's the upstream commit 7d2c7f5ad44d ("Add sof-v2.9 for
Intel hardware").
[Test Case]
1. Install linux-firmware version >= 20240318.git3b128b60-0ubuntu2.1
2. Install new noble/oracular -proposed alsa UCM conf package
3. Install 6.10-oem kernel
4. Go to audio setting to make sure the audio input/output device are not
dummy
[Where problems could occur]
It's simply an additional tplg file which only new kernel driver knows to how
to load.
========== alsa-ucm-conf ==========
[Impact]
Audio doesn't work on Dell new XPS laptops on Intel MTL platforms.
[Fix]
Kernel driver, ALSA ucm, and firmware fixes are required. For alsa-ucm-conf,
it requires the following upstream commit
1. c0a4df603786 ("sof-soundwire: Use one file for speaker codec")
2. 8e39917518b6 (sof-soundwire: Add basic support for basic cs35l56)
3. e87dde51d689 (sof-soundwire: Add basic support for cs42l43)
[Test Case]
1. Install linux-firmware version >= 20240318.git3b128b60-0ubuntu2.1
2. Install 6.10-oem kernel
3. Install new noble/oracular -proposed firmware-sof package
4. Go to audio setting to make sure the audio input/output device are not
dummy
[Where problems could occur]
The new alsa UCM file only take effect when new cs35l56 driver and
firmware-sof are loaded. The impact are restricted on cs35l56 only.
