I think you make alsa do this on playback. Something like this might
work (untested)
pcm.!default {
type plug
slave.rate 48000
slave.spdif
slave.channels 6
route_policy duplicate
}
If your sub does not have a lowpass filter you can use a more elaborate
setup and use http://alsa.opensrc.org/Ladspa_%28plugin%29.
