and later comments
[Test]
Tested on Intel LNL:
1, hear the sound from
$ speaker-test -c 2
2, make sound and recorded, replay the file:
$ arecord -f cd test.wav
$ aplay test.wav
3, press speaker-mute and mic-mute key, the OSD are shown,
and the LED is on when it's muted.
4, plugin headset and restest the steps above.
[Where problems could occur]
It may break cirrus audio support.
Noble/Oracular/Plucky support this platform, Plucky already got the
firmware.
