Comment(by coling):

 Yes I think this is a valid closer Tanu.

 For reference, I recently helped to solve this problem on my own h/w.

 The error was a combination of three problems: one in the h/w itself, one
 in the alsa driver and one in the alsa userspace library.

  * The hardware did not follow the HDA spec and muted the device when it
 was the slider was set to 0.
  * The driver did not have a quirk defined for this.
  * The library did not pay attention to the quirk when it was added.

 So there are a few commits needed to fix it:

  * kernel:
 [http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commit;h=de8c85f7840e5e29629de95f5af24297fb325e0b
 de8c85] and
 [http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commit;h=a74ccea51d4314632a81d568d59bf885e5b09d93
 a74cce] (but obviously this is specific to my h/w - yours may need similar
 fixes if it doesn't have them already)
  * alsa-lib: [http://git.alsa-project.org/?p=alsa-
 lib.git;a=commit;h=2f6206da0c1ff88235e6eca0077343f22a4b43ee 2f6206]
