What's A Good Way To Handle Multiple /dev/dsp's?

kronoman asks: "I've got a multiple-soundcard setup (three cards, four DSP devices) under Mandrake 7.0. Currently, I have an Ensoniq ES1371 on /dev/dsp0 and /dev/dsp1, an SB AWE64 on /dev/dsp2 and an AU8830 on /dev/dsp3. I'm already using ESD to send all ESD sound (especially xmms/mpg123) to /dev/dsp3, and timidity and kmidi use /dev/dsp1. I want to use /dev/dsp2 for emulator output and /dev/dsp for system sound and programs not smart enough to be able to put sound anywhere else. Unfortunately, most of my emus only want to output to /dev/dsp (in particular, UAE, Bochs, Snes9x). Is there a way to either A) get those emus to send output to /dev/dsp2 or B) get kaudioserver/kwmsound to output on a different DSP device (can't seem to find it in the docs, don't know enough C/C++ to find it in the source without some clue what to look for)"
