I'm having trouble getting sound out of mplayer for dvd-playbck. Soundcard is a good old SB audigy. The strange thing is, mplayer can do sound for mp3's fine (although I'm mostly using xmms for mp3s). I can even watch ( and listen to) trailers from apple.com with the mplayer plugin. So why is it just not working for dvd playback?
I actually get either a staticky sound or a low pitch buzz depending on wether or not I turn on the 'Audigy Analog/Digital' switch in kmix. I'm also using alsa, generally, although I did try telling mplayer to use other sound drivers with no luck.
I even know that my speakers are working (5.1 setup) since I can control rear/front volume through my little hardware volume control knob.
