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?
