audio filter lavcac3enc issue

[andrea3000@…]

There is an issue with the new version of audio filter lavcac3enc (introduced in r30285 of mplayer).
With an older version (r30223) I was able to use this filter which outputs an ac3 stream that my decoder (logitech z5500) correctly decode as dolby digital.
With the new version of the audio filter (from r30285 to the latest), the audio stream output is ac3be and my decoder is unable to decode it.

I paste the verbose output of a test I have just done; I use a combination of pan filter and lavcac3enc filter to convert a 7ch truehd audio track to 5ch ac3 track that can then be sent through s/pdif. I have always succesfully done this with mplayer revision 30223.
These are the options I use:
-ao coreaudio -channels 6 -af pan=6:1:0:0:0:0:0:0:1:0:0:0:0:0:0:0.45:0:0:0:0:0:0:0.45:0:0:0:0:0:0:0.8:0:0:0:0:0:0:1:0:0:0:0:0:0:0:0:0:0:0:0,lavcac3enc=1:448:3,channels=6 -ac -v fftruehd /Volumes/Dati/Audio\ demo/hd_dolby_truehd_channel_check_lossless.m2ts

and this is the verbose output:

I hope you can help me...I tried almost everything that came into my mind..

Hm? Isn't it a question of the sound card whether ac3be is supported?
Next, I think the real issue is the channels filter which shouldn't be there, the output of a working version would help a lot here.
Lastly, you can force little-endian ac3 by adding the format=ac3le filter.

Forcing little-endian everything works as before...thank you very much!
I still don't understand what is the problem...my sound card is a realteck ALC889a...it sounds strange to me that it doesn't support ac3be..
Thank you again!
