Hp spectre x360 静音麦克风按钮不工作且音量按钮上的 LED 指示灯不亮

我目前在我的 hp spectre x360 上使用 pop_os 20.04 LTS。

尽管所有其他音频按钮都正常工作，但我的麦克风静音按钮不起作用。此外，所有带有 LED 指示灯（麦克风静音和音量静音）的音频按钮均不亮，但我的大写锁定 LED 亮起。

我对 Linux 还不太熟悉，所以不太熟悉按键如何绑定或映射。

xev这是我按下静音、调高音量然后按下麦克风静音时的输出：

acpi_listen按相同顺序的键也会输出：

button/mute MUTE 00000080 00000000 K
button/volumeup VOLUP 00000080 00000000 K

sudo showkey -k按下相同顺序的键的输出：

keycode 113 press
keycode 113 release
keycode 115 press
keycode 115 release
keycode 240 press
keycode 240 release

输出自xmodmap -pke | grep Audio：

keycode 122 = XF86AudioLowerVolume NoSymbol XF86AudioLowerVolume
keycode 123 = XF86AudioRaiseVolume NoSymbol XF86AudioRaiseVolume

keycode 234 = XF86AudioMedia NoSymbol XF86AudioMedia

我已经尝试过：

gsettings reset org.gnome.settings-daemon.plugins.media-keys volume-mute

知道这是什么原因造成的吗？

另外，为什么 的键码与 的sudo showkey -k 输出不同？xmodmapxev
