I don't know if this directly answers your question, but from sound(4):

hw.snd.default_unit
	Default sound card for systems with multiple sound cards.  When
	using devfs(5), the default device for /dev/dsp.  Equivalent to a
	symlink from /dev/dsp to /dev/dsp${hw.snd.default_unit}.

FWIW, www/linux-f10-flashplugin10 is using /dev/dsp0.0 on my system at the
moment.
