[MPlayer-dev-eng] [PATCH] AC3/DTS passthrough on big endiansystem, not test

[? ?]

big endian stuff is highly related with hardware such like sound card, 
specially for audio digital output, I don't think simulation test should 
work.
if someone has a G4/G5 or old model Mac mini or other ppc machine with audio 
digital output and a decoder, it could be tested.
