On my System though, I have to additionally specify the correct alsa 
channel. Only one (0,1) accepts 6 channel input, the other two (0,0 and 
0,2) accept only 2 channel input, and play the 6 channel input at 1/3rd 
speed, as always three channels get sequentially mixed into one

in addition to -channels 6 -af channels=6 try -ao alsa:device=0.0 or 0.1 
or 0.2 (IIRC the syntax, don't have access to my machine right now).
