My guess is you're running KDE, right? Try mplayer -ao arts
Arts is a sound mixer, which allows you to play more than one sound at a time.
Some soundcards, i.e. the Soundblaster Live! does this in hardware, so you
never have to worry about that.
The nasty bit about arts is that there's often a slight delay in the sound.
In your KControl center, go to the audio properties. There's a setting that
specifies how long arts will be idle before suspending. The default is 60.
In other words, you have to wait 60 seconds after using sound through arts to
use your sound card directly (what you would like to do for movies). Set
this to something more sensible like 1 second.
Stupid I know, but it's getting better slowly. I wish they would write the
sound drivers to do this directly (maybe Alsa9 can, anybody?) so we don't
have to waste time dealing with rubbish like esd and alsa.
Hope this helps
