I don't know much about alsa (the docs tend to confuse me), but I do
know that mplayer can output to any existing alsa PCM. For example, if
I define a custom PCM in my .asoundrc called blah, then I can use that
with mplayer -ao alsa9:blah

In your case, this might be as simple as -ao alsa9:plug:dmix.

Hopefully that'll be enough for you to work from.
