Are you using PulseAudio? If so, try looking at the sound settings with
pavucontrol, the official PulseAudio configuration utility (in the
package extra/pavucontrol).

Correct me if I'm wrong, but if I remember correctly, the Gnome sound
manager and pavucontrol are different programs. In my experience, I have
had the best luck using pavucontrol to configure sound.
