** Description changed: - [Kernel SRU] + [SRU Justifications] + + ========== kernels ========== + [Impact] On Dell's Precision 3550, Intel MTL platform, the MIC-Mute function is working but the LED(on F4) state is not changed accordingly. [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/ + There's no problem on the same series on RPL platform.

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.
