I added a section here.
http://alsa.opensrc.org/index.php/.asoundrc#Joining_devices_to_make_multichannel

My code is derived from the documentation of multi plugin found here
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html

except instead of defining separate route and multi plugins, I nest all the
plugin defs so that only one set of $CARD,$DEV,$SUBDEV parameters are
required. As you see in the above example, if you have fixed devices the
setup is much less verbose.
