1. it looks like mplayer tried sdl,arts,sdl,esd and 
then settled for null (no sound) audio output driver as last resort

some basic checks,

is another process using your device /dev/dsp?
lsof | grep /dev/dsp
from log looks like it complained about device being busy

does your sound work in other programs?

2. misc tab under preferences has the dvd device settings
default is /dev/dvd

this should be a symlink to your dvd device.

ls -l /dev/dvd will show this info

I dont use the gui myself so I cant tell you more about it.
