 Replying to [comment:5 Cimi]:

 > Center and LFE are reproduced in every speaker, while mplayer reproduces
 the center with the two front speakers

 Sorry, I don't follow?

 Could you please do the pulseaudio -vvvv thing I mentioned? It will
 explain in detail how we do remixing.

 Also note that MPlayer doesn't really expot channel mapping information to
 its backends. The channel mapping the PA backend synthesizes for the audio
 streammight not match up what the sound file you have exports. This is a
 limitation of MPlayer.

 Use GStreamer. The GStreamer driver knows about channel mappings.
