I found the solution here: http://mpd.wikia.com/wiki/Configuration

I created a file /etc/asound.conf, with the following content:

pcm.dmixer {
  type dmix
  ipc_key 1024
  ipc_key_add_uid false
  ipc_perm 0666                       # mixing for all users
  slave {
    pcm "hw:0,0"
    period_time 0
    period_size 1024
    buffer_size 8192
    rate 44100
  }
  bindings {
    0 0
    1 1
  }
}

pcm.dsp0 {
  type plug
  slave.pcm "dmixer"
}

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

pcm.default {
  type plug
  slave.pcm "dmixer"
}

ctl.mixer0 {
  type hw
  card 0
}
