Comment (by cehoyos):
The sample you uploaded is to short to do any test imo, I tested with a
file that you should be able to find with Google:
{{{
$ ffmpeg -i Test\ AC3\ v2.0.avi -af "aresample=matrix_encoding=dplii" -ac
2 out.wav
$ ffmpeg -i Test\ AC3\ v2.0.avi -af "aresample=matrix_encoding=dplii" -ac
2 out.ac3
$ ffmpeg -i Test\ AC3\ v2.0.avi -af "aresample=matrix_encoding=dplii" -ac
2 out.eac3
}}}
I now set my receiver to "PLII" and played the three files over the
digital connection (HDMI): The surround sound sounded as expected
(surround sound although I used stereo files). I finally tested the wav
file over the analog connection and the stereo signal also played like a
surround signal.
Or do I misunderstand the problem?
