Mic mute led does not work on Matebook 14. about huawei-wmi

The driver doesn't depend on any LED driver, hence the name platform::micmute, it uses ACPI WMI to control the LED and then uses ledtrig_audio to hook it up with ALSA. However, I will look more into this log. Meanwhile, could you please provide a dmesg log with the issue.

Do you have /sys/devices/platform/huawei-wmi/leds/platform::micmute in your system? Can you control the LED by writing to /sys/devices/platform/huawei-wmi/leds/platform::micmute/brightness?

Aha I don't see any codecs in your Gento lsmod. Realtek sound codecs are used to enable the ledtrig_audio. Taken from your Arch lsmod snd_hda_codec_generic,huawei_wmi,snd_hda_codec_realtek. Make sure you have enabled sound. The LED should work though but not through ALSA. You should be able to turn it on/off manually.

Thanks! I got it worked today. I tweaked a little in my kernel config. Previously I built the codecs in the kernel. Now I build it as a module. Then the led works. I also changed some other settings in kernel config, but I think building the codecs as modules solved the problem. :)

Glad to hear that
