For must crappy sound cards that do not support hardware mixing, it may be necessary to configure also to perform software mixing so that MPD and Gnome don't fight over control of the sound card.

sudo gedit /etc/asound.conf



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

pcm.dmixer {
  type dmix
  ipc_key 1234
  ipc_key_add_uid false
  ipc_perm 0666     # mixing for all users
  slave {
    pcm "hw:0,0"    # use on board sound card ("aplay -l" might help your figure this out)
    period_time 0
    period_size 1024
    buffer_size 4096
    #rate 44100
  }
}
