Public bug reported:
I don't know if this is an alsa-driver or kernel issue, so I let you
decide.
There is a touch-sensitive mute led on my laptop which have two colors: red
when sound is mute and blue when it isn't.
The problem is that when sound is mute (red led) and that the sound card is
automatically disabled for power-saving, then the led become blue.
You can imagine that this is annoying because each time I'm looking at
my keyboard I think that sound is not mute !
(sorry for my English)
