By default, mplayer tries to open the device "default" for 2 channels, and
the device "surround51" for 6 channels (with a fallback to "default").
Therefore, you just have to set up your .asoundrc so that surround51 points
to hw:0.1.

On the other hand, I do not see the need for -af channels=6: on my system,
everything is fine without it.
