i pri men e taka, tova e mai samo za hardware decoding (SB Live i dr. 
takiva).Kolkoto i da mrazja eto malko copy/paste ot doc na mplayer:
2.2.2.2 Hardware AC3 decoding

You need an AC3 capable sound card, with digital out (SP/DIF). The 
card's driver must properly support the AFMT_AC3 format (C-Media does). 
Connect your AC3 decoder to the SP/DIF output, and use the -ac hwac3 
option. It is experimental but known to work with C-Media cards, 
Soundblaster Live! using ALSA (but not OSS) drivers and DXR3/Hollywood+ 
MPEG decoder cards.

a provba li s -channels 6 -af=channels=6:6:0:0:0:2:0:4:1:1:1:3:1:5 , 
koeto za obiknoven stereo format pravi 6 virtualni kanala kato kopira 
dvata originalni na drugite (tova ako ne e software switch zdrave mu 
kazi...). Drugoto e dali si unmute-nal kanalite koito pisah i dali si 
uvelichil volumeto?
Za filmi kodirani s AC3 codec raboti bez -af=6:6:0:0:0:2:0:4:1:1:1:3:1:5 
samo s -channels 6
Ako ne znaesh kak e kodiran filma, to konzolnata versia na mplayer dava 
dosta info po vaprosa .
