With ALSA you can set up the dmix plug:

---------- .asoundrc --------------
pcm.mix {
  type dmix
  ipc_key 1024
  slave {
    pcm "hw:0,0"
    period_time 0
    period_size 1024
    buffer_size 8192
    rate 44100
    format "S16_LE"
    #periods 128
  }
  bindings {
    0 0  # from 0 => to 0
    1 1  # from 1 => to 1
  }
}

pcm.!default {
  type plug
  slave.pcm "mix"
}

pcm.dsp0 pcm.default
---------- end of .asoundrc -------

And then use mplayer -ao alsa9:mix if your sound hardware doesn't
support hardware mixing.
