[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.

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.
