now I (partially) remember, the correct command line is something like 
-ao alsa:device=hw=0.1

And yes, I was able to play DTS 5.1 (from DVDs, no AVI though since I 
never encountered them), but I mostly stay with AC3, as DTS still 
sometimes has some issues and I don't bother inquiring them that much as 
I should :(

Another thing, -af channels=6 was not needed for my on-board sound 
solution (nvidia nforce4 ultra chipset, don't know the make of the sound 
chip anymore), but due to a lightning stroke this thing gave up and now 
I'm using a terratec, where -af channels=6 is mandatory, as otherwise 
surround comes only from some loudspeakers, (IIRC rear right, front 
right and center or whatever), and definitely not in the right order.
