With kernel-3.2, LED on a mute button reversed its function. When sound is muted,it is off, when sound is unmuted, it is on. With 3.1.6, works as it should.
It seems that commit https://github.com/torvalds/linux/commit/e2ef36c688d5844a986424c3194bd33212c...
(originated from "[PATCH] ALSA: hda: invert mute led polarity for HP laptops" http://mailman.alsa-project.org/pipermail/alsa-devel/2011-December/046862.ht...)

Link to Bugzilla issue I have opened : https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5505
Output of alsa-info.sh is attached there, and some more info.
If you need more information, I'll be happy to provide it. Would output of dmidecode be useful in any way? Please cc me, I am not subscribed to the list.
The output of dmidecode would definitely help.
Abraços, Gustavo
