I have a Lenovo laptop (p14s).
On the F1 and F4 keys, there are LEDs.
F1 is for the speakers, and F4 is for the microphone.
When I use Fn + F1, the speakers on my laptop are muted, and the LED is glowing. When I use this shortcut, it's the opposite. Unmuted and not glowing F1 key.
It doesn't work that way with the microphone (F4 key).
There is an OSD popup that indicates whether the microphone is muted or not, but the LED is always turned ON.
I use KDE Plasma.
When I use those shortcuts, icons on the taskbar change. There is a crossed-out speaker, and the same is for the microphone. But still, the F4 LED is on, no matter what the icon on the taskbar says.

I am having the same issue.

I've had the same issue with my Thinkpad T14 Gen 2a.
Not sure if it is possible in KDE, but one can manually set the LED (assuming THINKPAD_ACPI module is enabled, as it is in the default Arch kernel).
I use the following script, triggered by XF86AudioMicMute, in sway, to both provide the OSD and set the LED state:
#! /bin/bash
icons="/usr/share/icons/breeze-dark/devices/22/"
/bin/pamixer --default-source -t
if [[ $(/usr/bin/pamixer --default-source --get-mute) == "false" ]];
then
notify-send -i "${icons}"audio-input-microphone.svg "Microphone unmuted"
echo 0 | sudo /usr/bin/tee /sys/devices/platform/thinkpad_acpi/leds/platform\:\:micmute/brightness
else
notify-send -i "${icons}"audio-input-microphone.svg "Microphone muted"
echo 1 | sudo /usr/bin/tee /sys/devices/platform/thinkpad_acpi/leds/platform\:\:micmute/brightness

In my case, once I was able to turn it off, but I don't remember how. After reboot, it was (and is) glowing.
