Bug description:
[Impact]
We found some laptops from Lenovo 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, Lenovo and HP machines requires the additional
patches from
https://lore.kernel.org/all/20230814232325.86397-1-pierre-louis.boss...@linux.intel.com/
to fix the kcontrol naming problem to align with the MTL SoF FW.
[Test Case]
1. Make sure the latest firmware-sof is installed.
2. press mic-mute hot-key and check if mic-mute is enabled or not by the OSD
icon.
3. 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.
