That's not entirely correct. There are more 5.1 formats than AC3/DD like 
e.g. flac 5.1. On the Windows world there are also a lot of games that can 
produce 5.1 sound, don't know if that's possible on linux yet though. In 
these two cases an on-the-fly encoding to ac3 or even better dts would makes 
sense as well. 

But I do agree that the focus should be on pass-through first since playing 
ac3/dts 5.1 from a movies would the use case in 95% :). 

(me can't wait to see the ac3/dts led on my external player with pulse, 
currently I have to bypass pulse completely with mplayer/alsa to get 5.1 
since the only connection between my workstation and my external 
decoder/speaker setup is an spdif cable ..)
