Both are available in the Linuxtech repo for Centos 6. http://pkgrepo.linuxtech.net/el6/release/ These are both traditional ALSA mixers that ignore Pulseaudio and provide you directly with the hardware audio controls. If (like myself) you have no use for Pulseaudio then you might consider uninstalling it, I wrote a HOW-TO about it here: http://scientificlinuxforum.org/index.php?showtopic=618 Andy
