Specifying default alternate sound device?

Is there any easy way to specify a default alternate sound device (eg,
/dev/dsp1). I have both onboard sound (/dev/dsp) and a SB Live card
(/dev/dsp1), but I don't use the onboard sound. It's really frustrating
to try to configure every single application (that uses sound) to use
/dev/dsp1 instead.

Is there some safe/easy trick to set a general rule that all/most apps
will follow, so that they use /dev/dsp1 instead?

I'm using 5.1-RELEASE.

Thanks,
