Hmm I'm sure its somewhere on the ML.
Heres (part of) my setup. I make my .asoundrc include files from a config
directory. Much easier to try one thing or the other by including different
snippets of config.
.asoundrc
# Alsa top level configuration file
</home/me/asoundrc.d/hda_dmix_split>
then in /home/me/asoundrc.d/hda_dmix_split
# Define multichannel dmix

slave.pcm "hw:0"
slave.channels 4

slave.periods 4
slave.period_size 4096
