ThinkPad P14s Gen 5 AMD micmute LED is not working sometimes.

[pma1]

The mic and sound output works fine. The mute LED works fine. But when press Fn+F4, the mic-mute led is not working sometimes after bootup. The failrate is like 1/10.

Tested with latest alsa-ucm from git, it's reproduced. /sys/class/sound/ctl-led/mic/card1# cat list 7

amixer -c 1 controls

echo 'Capture Switch' > detach

echo 'Mic ACP LED Capture Switch' > attach

/sys/class/sound/ctl-led/mic/card1# cat list 17
