I tried the latest CVS (2005-04-03, ~12:00) but unfortunately the
problem is still there. The internal libfaad is silent for the 2
and 6 channel files. The external libfaad plays at least the 2
channel file correct, but for the 6 channel file libfaad decodes
8 channels.

The good news is that I've just figured out that the hack in the
external libfaad:

|    if (hDecoder->fr_channels == 6)
|        break;
(libfaad/syntax.c)

from a previous mail actually solved the problem completely! With
external libfaad and -channels 6 I get 3 different stereo streams
(front, rear, center/lfe). I must have been too tired that
evening to play with -channels and swap the surround slot...
