/*
As we ran onto an issue of having different volume levels for mono streams
and stereo streams we are now handling all the stereo panning ourselves.
Each stream now has two sources - one panned to the left and one to the right,
and uses two separate buffers to store data for each individual channel.
For that we also have to reshuffle all decoded PCM stereo data from LRLRLRLR to
LLLLRRRR (handled by CSortStereoBuffer).
