[Impact]
We found some laptops from Dell and HP with Intel MTL platform suffer the same MIC-Mute led not working problem just like lp:2049569.
[Fix] lp:2049569 adds switch/enum type of control on IPC4 to communicate correctly with MTL SoF FW. However, It requires the additional patches from https://<email address hidden>/ to fix the kcontrol naming problem to align with the MTL SoF FW.
[Test Case]
1. press mic-mute hot-key and check if mic-mute is enabled or not by the OSD icon.
2. The mic-mute led should be ON when mic-mute enabled, OFF when disabled.
[Where problems could occur]
It's only required for new sof-audio-pci-intel-mtl driver. The impact should be restricting. We may need more MTL machines to make sure the behavior is the aligned.
