Sorry for the delay, it's been a busy weekend ;)

You can just run "mplayer <file>", if you need to force ALSA (so you can
check if it's a problem with ALSA as it was my case) you can add -ao alsa,
so it would be:

  mplayer -ao alsa <filename>

Mplayer is usually smart enough to decide what to do without any further
action on the user's side, however as someone said it's a very complex
program that can do almost anything in which regards playing media files,
that's why the man page is such a huge beast. If we manage to identify the
bug and reproduce it consistently then that's a huge step towards finding a
solution.

By the way, what mplayer version are you using?
