>&kmix; usage is straightforward. Every mixer control that your soundcard provides is represented by a volume slider. Mono controls have a single slider, stereo controls can have either one or two sliders, depending on your choice. Additionally there is a panning slider at the bottom of the &kmix; window. If you have more than one soundcard, a list will be displayed on the top of the window, where you can choose between your soundcards. <screenshot>
