Hy,

Please review this patch.
I generated a custom Ubuntu 10.04.3 live CD with containing the patched alsa-utils script in /sbin directory.
When I booted this custom live CD, my desktop machine Nvidia soundcard is not muted by default (see bug 564472 for details). I am absolute sure this patch will resolve the mute problem for this Intel N10 soundcard too.
I added both the Intel N10 soundcard experienced muted channels and the Nvidia soundcard experienced muted channels with the patch.

I have got a question if you accept this type fix with final patch and perhaps commit this fix Lucid and Oneiric branch:
What method are better to fix this problem? Use the switch_control method to only switch the muted status from off to on, or use the unmute_and_set_level method this new channels and setting for example with a 80% volume value?

Attila

Bug description:
  Dear Developers,

  In Ubuntu 10.04.3 release if an user booted with the live CD, default the live system with following volum,e meters are default muted, I copyed amixer names:
  'Front',0
  'Surround',0
  'Center',0
  'LFE',0
  If I launch with GNOME Volume Control preference tool, mincreasing the output slider and uncheck the mute checkbox, the problem is resolved.
  Of course, this problem fixing is important for a11y related, because a screen reader user is important to default hear the screen reader audio output.
  I don't no yet this problem are present with newest Ubuntu releases this soundcard chipset, and I not often possible to use this machine with testing this problem.

  I attaching two amixer text file, first file is showing the original
  result, second shoving the results after I unchecked the mute checkbox
  with GNOME Volume Control preference tool.

  To easyest your work, I doed a diff output with two text file with diff -u command, see the results:
