[Fix] There's no problem on the same series on RPL platform. It needs MTL specific SoF driver and controls to support the registered mixer switch. It requires the patches in https://lore.kernel.org/all/20230919103115.30783-1-peter.ujfal...@linux.intel.com/ and https://lore.kernel.org/all/20230814232325.86397-1-pierre-louis.boss...@linux.intel.com/ [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. ========== firmware-sof ========== [Impact] The mic-mute led not working on Intel MTL powered laptops. [Fix] For firmware-sof, it required the upstream commit fdc884baa4b3 ("Add sof-ipc4-v2.8.1/mtl/, intel-signed + community") and the sof-hda-generic-2ch.tplg from v2.8.1 to make sure the ipc4 topology and control matches with the updated driver. [Test Case] 1. enable -proposed pocket and install firmware-sof-signed 2. press mic-mute hot-key and check if mic-mute is enabled or not by the OSD icon. [Where problems could occur] The updated sof-mtl.ri and the sof-hda-generic-2ch.tplg are shared by all Intel MTL platforms. Need to verify audio function on MTL enpowered machines.
