could you provide a quick hint on how to test it? I rebuild xine-lib
(add a debug printf to make sure changes of the .so are used by xine).

I tried to play this file:

$ ffprobe ~/Downloads/Surround\ Sound\ Test\ PCM\ 5.1.m2ts 2>&1 | grep Audio
Stream #0:1[0x1100]: Audio: pcm_bluray (HDMV / 0x564D4448), 48000 Hz, 5.1(side), s16, 4608 kb/s

Added to ~/.xine/config this line:

audio.output.speaker_arrangement:Stereo 2.0

but the result remains the same (wrong downmixing). Sometimes my
setting is overwritten for some reason, I don't understand.
