Well you never said what sound card you have, or what driver you're
using (whether you're using ALSA or OSS).  You should use ALSA if
possible (and it probably is).  This is what works for me, both with my
SB Live and nforce2-based motherboard (AC97):

   mplayer -ao alsa -ac hwac3, dvd://

My ~/.mplayer/config looks like:

        ao=alsa
        ac=hwac3,
        srate=48000
        af-adv=force=1

(The latter two lines don't concern AC3, but if you play MP3s with
mplayer, this was essential for me to get good quality with my nforce2.)

Cheers,
Jason.
