[Impact]
Audio doesn't work on Dell Pista/Diablo MTL platforms.
[Fix]
Kernel driver, ALSA ucm, and firmware fixes are required. For firmware-sof, it's the upstream commit 7d2c7f5ad44d ("Add Intel SOF2.7.2 topology files").
[Test Case]
1. Install linux-firmware with the FW files from upstream https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=57077702373e7ef40f0ca197724428d614bd92f8
2. Install alsa UCM file from upstream https://github.com/alsa-project/alsa-ucm-conf/commit/e87dde51d68950537f92af955ad0633437cc419a and https://github.com/alsa-project/alsa-ucm-conf/commit/8e39917518b62cce44d098bd6fe5d2c1b41f92bd
3. Make sure the linux kernel version is later than v6.9 or has the https://github.com/thesofproject/linux/pull/4829/commits backported
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 Pista/Diablo 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 with the FW files from upstream https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=57077702373e7ef40f0ca197724428d614bd92f8
2. Install 6.10-oem kernel which includes https://github.com/thesofproject/linux/pull/4829/commits
3. Install new firmware-sof with new tplg file sof-mtl-cs42l43-l0-cs35l56-l23.tplg
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. |
