Hi,

It just started to happen recently, not sure when, that my laptop boots with the LED off for the MIC (means MIC is enabled).

Then at system start (using systemd, alsa, no pulseaudio) the LED turns on and MIC is off. If I check alsamixer, I see the mic is not muted, volume is up and I see the devices. I do have audio in the system and if I press the MIC button (using Fn or not) it just does not work.

It looks like I cannot turn on the MIC (turned off when system starts) and even though alsamixer says that is working it is disabled. If I speak, it does not work. Apps does not recognize the mic enabled.

I am using i3 at the moment, but same on KDE. Kernel 3.15.0-rc8

Here is some information. Any ideas will be appreciated, thanks in advance.
