alsa-project/alsa-ucm-conf issue #100 was opened from miquecg: I'm running Arch Linux with `alsa-ucm-conf` 1.2.5.1. This problem was present in previous versions and it's being discussed on a [forum thread](https://bbs.archlinux.org/viewtopic.php?pid=1977273) among other things. So the problem is that microphone LED is always ON but mute/unmute behaviour still works.
