not quite.

WHen I do:

mplayer -af channels=6:4:0:0:1:1:0:2:1:3 stereo.mp3

all is ok. But typing channels=.... is inconvenient, so I'd like to add 
it to my config, but:

mplayer -af channels=6:4:0:0:1:1:0:2:1:3 dolby.avi

and it does crazy things. Center is silent, ant front is cloned to rear, 
just like in stereo. It does not check, if the channels exist.

Is there any way to apply some if expressions? I mean, when there are 
only 2 channels - expand it to rear, but when it's >=4, do nothing?
