Hi,
Using A2 sound system, in stereo mode, the first sound channel is L+R, the
second channel is 2*R. So the dematrix control should be SUMR instead of
SUMDIFF. Let's use SUMR for stereo mode, and use SUMDIFF for everything
else. (SUMDIFF is required for mono mode, because without it the right
channel would be silent).
