Have you played with the mixer portion of KMix at all?  There is a tab 
labled "switches" in the window that may do what you need.

You can also add a "Sound Mixer" applet to your panel that will put some of 
the options of KMix onto your panel in the form of tiny sliders...this has 
been useful to me.
