[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.
