Just bringing up a Centos-6 (x86_64, FWIW) and I can't find the mixer app... on my C5 box(es), double click on the speaker icon in the top panel and I get a mixer app appears on the screen. My new C6 box doesn't do that. I've installed all the PULSEAUDIO RPMS I can find, but still nothing. what am I missing here? thanks! Fred
