Use any search engine. This is a common problem and unrelated to MPlayer.

There's another problem here, something else is occupying the sound device.

I think you should learn to use strace. Insert strace -eopen -f at the
beginning of your command for starters and watch the output for any failed
file open operations.

My other theory is that some of the XAnim real codecs (*.so*) require
additional libs on your system, which you don't have, but you'll be able to
see that on strace. Either that, or use ldd on them.
