what is an HDSP card? if that's like some plug and play thing than you
could check in /proc/asound and see if a file named after the card comes
and goes when you plug and unplug it.
then maybe something like:

#!/bin/bash

if [ -e /proc/asound/$HDSP ]; then
	qjackctl --preset=$HDSP
else
	quackctl --preset=$ICH

fi
