Thinkpad X1 Carbon 静音指示灯不工作

我在 Thinkpad X1 Carbon Gen 13 上安装了 Archlinux 和 KDE. 我安装了sof-firmware, 声卡和静音按键在系统上工作正常. 但是静音指示灯不跟随系统音量. 尽管我可以手动地通过以下命令打开它:

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

跟随 Laptop 页面, 我运行

$ lsmod | grep snd_hda_intel

snd_hda_intel          69632  0

不过 "grep Codec /proc/asound/card*/codec* " 的结果只有一行

Codec: Intel Lunar Lake HDMI

我尝试给 /etc/modprobe.d/mute-led.conf 添加

options snd_hda_intel model=thinkpad

然而指示灯依然不正常工作.
