To dump means to not play anything, but to write the input data to a file.
That's probably not what you want. You can output decoded audio with -ao
pcm

If you really want to dump, you have to specify what to dump, e.g.
-dumpstream or -dumpaudio in addition to -dumpfile, which only sets the
filename.

Sorry, i don't quite understand. Mplayer can however not mix two sounds.

Yes, but probably not when dumping, as dumping means _not_ to play.
