[MPlayer-users] Sample format big endian AC3 not yet supported / AC3 5.1 is played as AC3 2Ch 8 (?) bit with 1 (!) bps (???)

[dwe]

I just bought a Low-End AC3-Amplifier at Wal Mart Germany, brand is their own, named "Durabrand" (only 90,- ? including 6 speakers, sound is astonishingly clear regarding the price)

Sound works fine, also via SP/DIF, Winamp plays fine, with Windows media player and moonlight audio codec also AC3 sound plays fine with all six discrete channels.

But I want to use mplayer (of course) to play the movie, but I get this Error message:

Soundcard is a Hoontech with some Yamaha YMF chip, but i don't think that's important.


In this forum I found only messages from January to march, claiming this bug were fixed, but obviously it's not.

I get some sound, but nothing hearable. Only an ugly loud white-noise-like noise with stuttering clicks. 

So i see two Problems: 

a) Big Endian format is not converted to little endian
b) mplayer insists on AC3 2.1 - but it's DEFINITELY AC3 5.1 !!!

Maybe the compiled windows version is outdated an the bug is fixed already?

Maybe you could update the compiled windows version that can be found here:
http://www.mplayerhq.hu/MPlayer/releases/win32-beta/
to Version 1.0pre2 (?)
(I am planning to move towards linux, but am still stuck to windows atm)


Is there already any solution to this problem?
Is someone out there able to send AC3 directly to his/her DD-Decoder using mplayer?
