KMix usage is straightforward. Every mixer device that your soundcard provides, is represented by a volume slider. Mono devices have only one slider, Stereo devices have two sliders. You are able to merge the two sliders of a stereo device to a single slider. Additionaly there is a panning slider at the bottom of the KMix window.
The volume sliders show the volume of the selected device. Top is maximum, bottom is minimum volume. The slider can have three background colors:
Normal No special situation applies to this device.
Black The device is muted.

The volume sliders have a context menu. Three entries are possible, but only the applicable are shown.
Mute [On,Off] Mute and unmute the the device.
(Un-)Split Show either one or two sliders. Only applicable to stereo devices.
