Thinkpad X1 Carbon 静音指示灯不工作

兔子吃窝边肉

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:

1. echo <span class="number" style="color: rgb(28, 0, 207);">1</span> | sudo tee /sys/devices/platform/thinkpad_acpi/leds/<span class="symbol" style="color: rgb(28, 0, 207);">platform:</span><span class="symbol" style="color: rgb(28, 0, 207);">:mute/brightness</span>

复制代码

跟随 Laptop 页面, 我运行

1. $ lsmod | grep snd_hda_intel
   
2. <span class="comment" style="color: rgb(0, 106, 0);">---</span>
   
3. <span class="title">snd_hda_intel</span>          <span class="number" style="color: rgb(28, 0, 207);">69632</span>  <span class="number" style="color: rgb(28, 0, 207);">0</span>

复制代码

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

1. <span class="attribute">Codec</span>: <span class="string" style="color: rgb(196, 26, 22);">Intel Lunar Lake HDMI</span>

复制代码

我尝试给 /etc/modprobe.d/mute-led.conf 添加

1. <span class="title" style="color: rgb(170, 13, 145);">options</span> snd_hda_intel model=thinkpad

复制代码

然而指示灯依然不正常工作.
