echo "options snd-usb-audio index=-2" | sudo tee -a /etc/modprobe.d/alsa-base

ensures that the usb device will be always be secondary to any other
sound device.

The negative index mask was added to Debian's ALSA 1.0.8 packages and
was merged upstream into ALSA 1.0.9.

In GNOME this functionality is provided by gnome-volume-manager. You
can, however, also use the set-default-soundcard(1) script to set the
default device, then kill and respawn arts.

I can't speak for Kmix offhand.
