Aslainfo for the box with two CA0106 at http://www.alsa-project.org/db/?f=2b174514cdab6a985b71f0341b32e64e8a61bd49 This commit fixes the conexant cx5051 issue: http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commitdiff;h=29c5fbbcfefba5225a6783683c46c39e10877703 For Audigy/Creative cards, I believe that it is not a regression. It depends on the driver author, if mute is implemented. The higher layer like PulseAudio should use hardware mute or set the lowest volume.

Created attachment 580458 [details] alsa-info Description of problem: In Rhel6.3 with my audio card (ICH9 Conexant CX20561 (Hermosa)) I can no longer mute audio via alsamixer. The mute switch is missing on all available channels. Though I am able to mute with amixer set Master mute, pulseaudio mute also works. Version-Release number of selected component (if applicable): kernel-2.6.32-262.el6 alsa-utils-1.0.22-2.el6 How reproducible: 100% Steps to Reproduce: 1. alsamixer -c0 2. choose a channel, e.g. Master 3. press 'm' to mute Actual results: sound still audible audible Expected results: sound is not audible Additional info: Probably related only to spec. card/Codec. I tested couple of others with no issue.
