There's two ways that ALSA does sound mixing - hardware & software.
Hardware mixing requires your sound to have multiple DACs and for
ALSA to support them. Software mixing in ALSA is achieve through the
use of the dmixer plugin. Only ALSA-aware software can use it though.
Not all is lost, for OSS-aware software can be made to use ALSA without
loading ALSA's own OSS emulation layer through "aoss" which works
somewhat like artsdsp.
http://www.thepenguin.org.uk/alsa/ has setup instructions for an
"integrated sound card based on the intel i810 device" which doesn't
do hardware mixing.
