Hey guys,
my microphone LED is enabled all the time, no matter, if my microphone is actually on or off. The button itself works perfectly fine, it's literally just the light.
I tried everything, installed the latest firmware, latest bios version, even checked pipewire config, tried lts-kernel,
I'm completely helpless.
I even tried reinstalling arch and for a while, it actually worked. Until it didn't.
echo 0 | sudo tee /sys/class/leds/platform::micmute/brightness
This works, I can manually turn it off, but this solution sucks.
I can do a shell script that's always running in a permanent while loop, turning the button on and off, whenever I press it, but this solution also sucks, I don't want a shell script always running in the background.
SO WHAT CAN I DO?
Edit 3:
I actually solved it lol

1. Install ALSA utils (sudo pacman -S alsa-utils)
2. Open ALSA Mixer (alsamixer)
4. Find Realtek ALC27 sound card (card label may be HD-Audio Generic, it should have 5 channels)
5. reboot
6. profit
Edit: What I meant by until it didn't: At first, right after the re-install, I had the same problem I have now. Then I installed the latest firmware, rebooted, everything worked flawlessly. I continued my setup, but I didn't really do stuff that could influence my mic led. I installed discord, a few jetbrains IDEs, vscode, spotify, firefox, stuff like that. After 2 or 3 restarts, the led problem returned.
Edit 2: Found this https://bbs.archlinux.org/viewtopic.php?id=269871, it looks like there is a control interface in sys/class/sound/ctl-led/mic/mode, but I can't edit it
