alsa-info after boot

After booting the mute led is out of sync with the software mute control.

Which means: Pressing the mute led mutes the sound but the mixer still thinks that it is not muted. 

However after a suspend/resume cycle it is fine; the mute button does trigger the software mute control. (i.e the led and the mixer are in sync).

The output of alsa-info before and after the suspend cycle is attached.

This should be fixed in the latest kernel, as now it's using the generic parser code.  Please reopen if the problem still persists with 3.12 kernel.
