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.
[Other Info]
Need commits on 1.2.11 and 1.2.12 to fix the regression on rt13xx on old
platforms.
