Depends on the card. Some cards like my ens1371 based card have more than one 
playback device in which case you can do the routing via OpenAl.
Or you can use ALSA's software mixing module called dmix.
Or you can try artsdsp.

This is one area that MS get it right. WinXP uses DirectSound software mixing 
by default so it's a lot less trouble for Windows users. Hopefully Linux will 
get it right some day but arts and the like haven't been doing too well. (bad 
performance and buggy).

Of course if you have one of those nice emu10k based cards you can ignore all 
my advice - plug it in and it'll do the mixing in hardware automatically to 
one playback device.

Cheap hardware and standards ... sigh.
