Hard to say; your original description sounded like you're hearing 
either front-left/front-right or rear-left/rear-right. Can you identify 
which? Usually, music plays in the front pair.

Check your mixer settings and make sure the other channels aren't muted 
or low-volume.

You still need to post the full output of "mplayer -channels 6 ...". 
Otherwise, I have to guess at what's going on.
