alsa-project/alsa-ucm-conf issue #770 was opened from alexaryn:
`alsa-info.sh` output: https://alsa-project.org/db/?f=e74874770f91860edde30f1d42e33c106f2a1c32
I recently updated the software on my gentoo laptop, including the kernel. `speaker-test` demonstrates that I have audio output and that the mute button properly toggles the sound. However, the speaker mute LED, which used to work, just stays off.
I think this is related to the empty list in `/sys/class/sound/ctl-led/speaker/card0/list`. I think it should hold the value `10` for the Master Playback Switch.
My current ALSA is 1.2.15. Previous was 1.2.14.
My kernel is 6.18.32. Previous was 6.12.58.
The microphone mute LED works fine.
