[Solved] Mute led light doesn't work on Thinkpad X1 Carbon gen 13

Update: The mute LED light on F1 key works fine after an update.
--------------------
I installed Archlinux with KDE on my laptop (Thinkpad X1 Carbon Gen 13). The audio and mute key work well on my laptop, but the mute led light on F1 key doesn't turn on when I mute my compute. Though I can manually turn it on through

echo 1 | sudo tee /sys/devices/platform/thinkpad_acpi/leds/platform::mute/brightness

Following the Laptop page of ArchWiki, I ran the command

$ lsmod | grep snd_hda_intel 
---
snd_hda_intel          69632  0
snd_intel_dspcfg       45056  4 snd_hda_intel,snd_sof,snd_sof_intel_hda_common,snd_sof_intel_hda_generic
snd_hda_codec         229376  5 snd_hda_codec_hdmi,snd_hda_intel,snd_soc_intel_hda_dsp_common,snd_soc_hdac_hda,snd_sof_intel_hda
snd_hda_core          151552  8 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_ext_core,snd_hda_codec,snd_soc_intel_hda_dsp_common,snd_sof_intel_hda_common,snd_soc_hdac_hda,snd_sof_intel_hda
snd_pcm               221184  14 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec,soundwire_intel,snd_sof,snd_soc_rt712_sdca,snd_sof_intel_hda_common,snd_compress,snd_sof_intel_hda_generic,snd_soc_core,snd_sof_utils,snd_soc_rt1318_sdw,snd_hda_core,snd_pcm_dmaengine
snd                   163840  24 snd_ctl_led,snd_seq,snd_seq_device,snd_hda_codec_hdmi,snd_hwdep,snd_hda_intel,snd_hda_codec,snd_sof,snd_timer,snd_compress,snd_soc_sdw_utils,thinkpad_acpi,snd_soc_core,snd_pcm

The output of "grep Codec /proc/asound/card*/codec* " consists of only one line

Codec: Intel Lunar Lake HDMI

I tried to add

options snd_hda_intel model=thinkpad

to /etc/modprobe.d/mute-led.conf, but it didn't work.

Exactly same issue in my case as well. X1 Gen 13, F1 led doesn't work. Other led lights seem to work properly.

The mute LED light on F1 key works after an update.
