I use alsa, and I don't have a volume control applet on my Gnome Panel.
When I right click and select "add to panel", there is nothing that has to do with "sound", "audio" or "volume" in the list, and the "Indicator Applet" or "Indicator Applet Session" things have no volume controls, or properties that would let you enable any sort of volume control.
How can I get a volume control in Ubuntu, so I don't have to run aumix in a terminal or something?
So I've got the thing working now. But does anyone know why the new, fancy "Indicator Applet" volume control doesn't appear? The Gnome Volume Control Applet isn't as nicely featured, although it actually works.
I've been using Linux since Redhat 5, it's beyond me why these sorts of problems are still around. Someone should just put a damn "Volume Control" element in the list of things to add to the panel, even if it doesn't work, perhaps showing an error message.
