Bug Description
[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 sof-v2.9 for Intel hardware").
[Test Case]
1. Install linux-firmware with the FW files from upstream https:/
2. Install alsa UCM file from upstream https:/
3. Make sure the linux kernel version is later than v6.9 or has the https:/
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.
