Bug#1009628: linux-image-5.16.0-6-amd64: Wrong initial state of microphone muted LED on Thinkpad E14 (Gen 2)
I hacked together a dirty workaround, which I'm sharing just in case
somebody else with the same problem ends up on this bug report.
Since I'm using systemd and pulseaudio, and the microphone state
changes are correctly being sent to the kernel (I'm not exactly sure
who's responsible for this), I've created a small systemd service unit
that depends on pulseaudio and simply toggles the microphone muted
status twice. The pulseaudio unit is a user service, so this unit
needs to be a user service as well.
A temporary file is used to avoid toggling the microphone more than
once per boot.
$ cat /usr/local/lib/systemd/user/micropohe_led.service
[Unit]
Requires=pulseaudio.service
Description=Make sure that the microphone-muted LED on the F4 key
matches the actual microphone status
[Service]
Type=oneshot
ExecStart=/bin/sh -c "[ ! -f /temp/micmute-led-toggled ] && touch
/tmp/micmute-led-toggled && pactl set-source-mute @DEFAULT_SOURCE@
toggle && pactl set-source-mute @DEFAULT_SOURCE@ toggle"
[Install]
WantedBy=default.target
This service can be enabled for all users with "sudo systemctl
--global enable micropohe_led.service".

Bug#1009628: linux-image-5.16.0-6-amd64: Wrong initial state of microphone muted LED on Thinkpad E14 (Gen 2)
Package: src:linux
Version: 5.16.18-1

X-Debbugs-Cc: steven3k+deb...@gmail.com
Dear Maintainer,
I'd like to report that the initial status of the "microphone muted" LED on the
F4 key of a Thinkpad E14 (Gen 2) laptop is incorrectly set to on on boot, even
though the microphone is indeed not muted.
Pressing the key leaves the LED on but mutes the microphone. Pressing the key
again unmutes the microphone and turns off the LED.
All subsequent presses behave as expected (i.e., the LED matches the mute
status).
It look like the information that the mic is unmuted never gets to the module
that is handling the LEDs.
Manually turning the LED off via "/sys/class/leds/platform::micmute/brightness"
disables the LED trigger. Re-enabling the led trigger with "echo micmute >
/sys/class/leds/platform::micmute/trigger" re-lights the LED.
This seems somewhat related:
https://lore.kernel.org/alsa-devel/20210221115208.105203-1-hdego...@redhat.com/
Please let me know if I can help troubleshoot the problem. So far I was not
able to find any workaround.
Thank you!
